supersonic Avis 365

Worst service and fiber ever will never use them again and will also advise everyone not to use them😡😡😡😡

I honestly don’t even know where to begin with Supersonic.
I joined them just 2 months ago, and to be fair, the installation was seamless and everything was working perfectly. But that’s where the good experience ends.
Two days ago, my router suddenly stopped working. No warning, no explanation — just dead. This alone speaks volumes about the quality of equipment Supersonic provides to paying customers — clearly not built to last.
I immediately reported the issue, expecting urgency considering this is an essential service. Instead, I’ve been given nothing but the runaround. Every interaction leads to the same useless response: “please wait.”
Wait for what exactly?
I rely on my internet connection for work, which means this is not just an inconvenience — it is actively costing me money. And yet, there seems to be absolutely no sense of urgency or accountability from Supersonic’s side. No updates, no follow-ups, no solutions.
What makes it even worse is that when the equipment fails, you’re left to deal with the consequences on your own. There is no urgency, no care, and certainly no customer support worth mentioning.
What’s even more frustrating is how quick they are to expect full and on-time payment from their customers, but when it comes to delivering the service you’re paying for? Silence.
All I need is a simple resolution: a replacement router delivered ASAP so I can get back to work. It’s not complicated. But getting any kind of assistance or communication from Supersonic feels impossible.
At this point, I am beyond fed up with this level of service. If you’re considering joining Supersonic, just be aware — everything is great until something goes wrong. Then you’re completely on your own.
Absolutely unacceptable.

If i could give zero stars i would give minus 5.

Dear Supersonic,

I am writing to formally lodge a complaint regarding the complete failure of my internet service and the unacceptable billing associated with it.

To provide full context: my service was scheduled and activated in mid-February, as I arranged this in advance before moving into my apartment at the end of February to ensure I would have internet upon arrival. Despite this, when I moved in, I did not receive any working Wi-Fi linked to my account.

The only internet access available at the time was from the previous tenant’s connection, which was still active. This means that from the outset, I was billed for a service that was never actually provided to me.

Since the 24th of March, the situation has worsened further, and my internet has been completely shut down. From that date until now, I have had absolutely no service whatsoever.

For the past three weeks, I have contacted your support team every single day—often three to four times per day—only to be repeatedly told that “the matter has been escalated.” This has become an empty statement with no action behind it.

On every call, I am promised that a supervisor or senior technician will contact me. Not once has this happened. Not a single callback has been received.

Despite the total lack of service, I have been billed twice. Let me be absolutely clear: I have paid for a service that I have not received at all.

I have also gone out of my way to contact OpenServe myself—something that is entirely your responsibility—not mine. OpenServe has not confirmed any fault on their side and has instead directed responsibility back to Supersonic. This ongoing finger-pointing, with no accountability or resolution, is completely unacceptable.

I have even escalated the matter internally with one of your technical advisors, Jacob, who was expected to provide a higher level of support. Unfortunately, this interaction resulted in no progress whatsoever.

At this point, my patience is exhausted. What I have experienced is not “downtime”—it is a complete failure of service delivery. There has been no service. None.

I have already requested cancellation of my account, and I will now state my position clearly:

You are required to take one of the following actions immediately:

Cancel my account in full and refund me for the entire period I have been billed without receiving any service; OR

Resolve the issue and restore my internet service without any further delay.

If neither of these actions is taken promptly, I will have no choice but to escalate this matter further through the appropriate consumer protection channels.

I expect urgent action and a definitive resolution—no more empty promises, no more escalations without outcomes.

Regards,David de Klerk

CANCELLATIONS: 7 days in. Been phoning every day. They took over my fibre line - activated 5 March yet I cancelled the order 15 Feb. They have no active, valid orders in place but can't get them to cancel on their side/ release my line and provide proof. Logged tickets that were apparently escalated. Yet nothing has been done

Supersonice has the worst customer service , they have a bot chatting to you on WhatsApp referring you to their website where you dont even see much information on the dashboard.

Upon applying for the order I checked coverage in my area after a couple of days I called their call center I was advised then only that there is no coverage in my area. I had to call eversince then there was no communication from them.

I canceled the order on my end and obviously thought they'd cancel the order on their end because we can't proceed with the service. I have sent 2 emails, logged a ticket and multiple phone calls later. Not really getting help from them this order still shows pending on their side.

There is absolutely no customer service here. Seems like whoever is in charge of each process does not see their processes through. Plainly not doing their job. This was my first encounter with Supersonic and definitely my last.

The ticket I logged is the same ticket number the lady gave me whilst she said she is logging a call. Its just so astonishing. I am in customer service type of job and this? Is really bad for their business.

I do not recommend anyone to make use of their services

This is the worst service ever! I cannot begin to express how frustrating it is dealing with them. I have gone 4 days with no internet connection. I logged a ticket which they responded to by “resolved” I have tried calls, emails etc.
if I could prevent each and every prospective client from using their service, I would make it my life’s work to do so. I doubt if this company services will ever improve.

They are simply the Worst! I understand each and every negative review I have read about them. Too late I read these late💔.

In December 2025 I noted even though I only have a 100MB line, I get charged for a 500MB line. On the 17 December 2025 I opened the ticket. After many times calling the call centre I received a call back on the 6 Jan 2026 that they need to refund me and I must send them a proof of bank details. Which I did. The end of Janaury I was billed again for a 500MB line. I was told this will happen, but after 25 working days I will be refunded. Till today I have yeat to receive the money. The ticket was closed stating I am getting 500MB speed. I have provided Supersonic with numerous photos of line speed tests. They are truelly the worst ISP in Africa. Their call centre is just a way to block you from speaking to the people who really makes the decisions and dont care about the customer. I have logged one final ticket to them and then if I dont get this resolved I am going to go to ICASA. Dont ever support MTN or Supersonic.

Disgusting this company could not care less àbout the customer. Absolute waste of time. Have been with them since October pay for 150 up down, lucky if the speed is 10. So tired of contacting the technical help desk writing emails etc.... just to hear them blame something else. Get your act together Supersonic before you loose even more customers.

Supersonic answered my first complaint after a week . A week later same problem.WHY AND WE ARE PAYING FOR THE SERVICE. WHAT SEEMS TO BE THE PROBLEM A WEEK LATER REALLY

Pathetic service delivery from the supersonic team. No sense of urgency to their customers despite the number of calls or tickets pleading for urgent resolution. I was supplied a new ZTE router which stopped working . I had to trouble shoot for the team & advise them the router isnt working. All efforts to get my spare to be linked & have me atleast back online is falling on "deaf ear". Disappointed long time MTN customer

I ordered Supersonic Fiber over a month ago, and I’m really disappointed. They charged me for a service that I haven’t even used because the installation hasn’t happened yet. I’ve tried reaching out, but there’s no manager or supervisor available to talk to me. It feels really frustrating to feel stuck in this situation with no one to help. I just wanted to get my internet set up, but so far, it’s been a hassle. I hope they can figure out their

Pathetic service
If I could give them zero stars it would be more accurate. Changed my service with no notification, claiming they sent out e-mails in December, but all I received was my invoice. No internet because they didn't allocate data to me, promises to have the issue resolved, but after 2 calls and 3 tickets, still no internet. When you relocate, you have to change your address with them at least 3 times before they get it right. I'm definitely changing to a different service provider

Extremely unprofessional. If you get wifi and have to relocate within a year's time they will charge you R800.00 for cancelling instead of offering you a fee to install wifi on the new premises.

My company will never support these people again.
I advise everyone to stay away.

Paying Since December With No Internet – Still Not Connected
I moved to a different unit in the same building and requested my internet to be reconnected in the first week of December 2025. Today is the 21st of January, 2026, almost 2 months later, I am still without service.

Since December, I have endured endless calls, repeated promises of installation dates, and constant reassurances - none of which have been honoured. Despite this, billing has continued for a service I am not receiving.

Receiving a generic “welcome” message quoting a 7–10 working day (sent on the 12th of January,marking this the 8th day ) installation timeline is unacceptable when this issue has been ongoing for at least 2 months.

This is poor service delivery and a complete lack of accountability.

I am requesting:

A confirmed connection date

I am posting this publicly in the hope that it finally receives the attention it should have received long ago.

I was on a month-to-month Supersonic (via MTN) fibre service on the Vumatel network. The package was R299 for the first two months and R499 thereafter.

My account was suspended and later reactivated without my consent, and was ultimately terminated by Supersonic, not by me. Despite this, Supersonic later demanded R2 900, which includes multiple months of subscription charges after service suspension, contrary to month-to-month contract principles and the Consumer Protection Act.

A Vumatel clawback of R899 (for the router) was added. When I requested a full, itemised breakdown of the charges, Supersonic only sent screenshots showing a total balance, instead of providing a proper billing statement detailing dates, services, and individual charges. This is not transparent billing.

Customer support has been unresponsive and ineffective. WhatsApp agents stop replying mid-conversation, provide inconsistent explanations, and fail to resolve formal disputes. Repeated attempts to settle the account reasonably were ignored.

This experience demonstrates unfair billing practices, poor transparency, and disregard for consumer rights. Based on this experience, I cannot recommend Supersonic.

Im a supersonic client. I logged a call about WiFi not reaching rooms in my house. I followed up twice on the ticket and phoned 5 times only to be told that is not a service they offer! An absolute waste of time and money, avoid at all costs.

Would give 0 stars if I could. 4 days without internet. Logged 3 support tickets - no response. Unable to get through on phone as every time you enter your ID number it says it does not exist and cuts you off. Logged in to my account dashboard and says everything is fine. It is not. There seems no way to resolve this. DO NOT USE THIS COMPANY. CUSTOMER SERVICE IS APPALLING!

I would love to give Ngele his flowers.
He took ownership of the interactions from start to finish where other agent could have easily dismissed me.
Thank you for taking the initiative to keep me connected!

I would leave zero star if I could. The most horrific experience I have ever encountered. We have have had no internet connectivity for a week due to a billing error. Our service was cut off last week and despite having emailed and called every available channel, our ticket keeps getting closed with no resolution. We have emailed proof of payment dozens of times with zero acknowledgement and both my mobile number and my husband's number have been blockedso there is no way of following up with them. It is basically theft to take someone's money and not provide a service. In addition, my husband and I both work from home and this has had a severe impact on us both this past week. We cannot even cancel despite submitting a cancellation letter, no acknowledgement at all. When approaching a new service provider, we've been informed that MTN have to release the line before they can migrate us to their service. How do we do that when we cannot get any response from MTN Supersonic??

No star at all. Their service is horrible. Canceling your contract with them is absolutely more horrible. I hate supersonic with great passion I won't even recommend it to my worst enemy
