Worse than bad service, it’s non existent service

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

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 leave zero star if I could

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??

Shame on MTN for Supersonic! MTN - the apparent leading cellular provider in Africa, hiding behind the Supersonic screen of pathetic service delivery.

I've been with MTN for way over a decade and trusted them - therefore, when I was redirected to Supersonic via the MTN website, I stupidly ignored all the bad reviews and still went with them.

* JULY '25:
I applied, and in less than a week I was set-up and ready to go. I set my debit order date for the 8th of each month, and wondered what the fuss about Supersonic was all about.

They didn't bill me for anything this month.

* AUGUST '25:
They invoiced me for July + Aug, and stated that the amount needed to be paid by the 15th, even though I'd opted for the 8th as my payment date.

Before the 8th I went to my Supersonic dashboard, only to notice that it stated my account was in arrears, and provided a link for an instant payment.

I was confused - it wasn't the 8th yet, nor the 15th, so I followed the link in utter confusion, and paid them nonetheless.

The next day I realised that even though I had already manually paid them, they had still debited me too.

I emailed them to request that they return one of the payments - I included each and every single email address I could find online connected to Supersonic and MTN, but no logical response (if any) was forthcoming.

Eventually I got hold of someone on the phone, only to be told that they won't refund me, but I would be credited for the additional amount the following month.

And no, there was no apology, only some convoluted attempt at a justification. I wasn't happy, but needless to say - I couldn't really do anything about it.

Another significant issue with this particular month's invoice was the pro rata rate.
They stated that the service for July (the first month) was pro rata (@R289 [for the first 3 months] per month: 8th-31st July is R216.75), but they billed me for the random amount of R331.26.

* SEPTEMBER '25:
I was once again invoiced for the full amount, but they only debited me for some random amount that made no sense in regards to the math.

When I tried to question why I receive invoices each month, but never any statements indicating the payments I'd made - I was obviously met with silence again.

BY LAW, WE'RE ENTITLED TO A STATEMENT THAT INDICATES THE PAYMENTS WE'VE MADE.

By this stage, I'd had enough of their pathetic service - not to mention the various glitches I'd encountered with the connection that was regularly down, so I gave them a month's notice and told them to fetch their equipment.

Besides their pathetic 'sad to see you go' emails, I received another one stating that I'd be charged a clawback fee of R899.

Apparently I clicked on a T&Cs option saying that if I cancelled within a year, I'd pay this amount - I'm still waiting for a time-stamped link to those T&Cs.

When I requested a time-stamped link to it, they emailed me random screenshots of their T&Cs, but no actual proof that what they were saying was true.

I was also informed that I'd need to contact someone to make arrangements to return their router, or be charged R250 to have it couriered back. If not, apparently I'll be charged for the router as well.
But guess what... nobody is willing to tell me how much.

** FIRSTLY, where's my copy of this 'contract'?
I never received a copy of the T&Cs I had to click on during the registration process.

BY LAW - FOR A CONTRACT (INCL. T&Cs) TO BE VALID, BOTH PARTIES MUST HAVE A COPY OF IT.

Yes, T&Cs do count as a contract, but is worded in a way to protect the service provider, not the client.

It's also easier for them to secretly update the T&Cs at their whim.

** Secondly - I cancelled because of poor service delivery, so I queried via email why I'm being charged a cancellation clawback - only to be ignored again... of course.

** And thirdly - why do I need to post their router anywhere? They had local staff who came to rig up the system, so why can't I drop it off locally at their offices?

* OCTOBER '25:
I disconnected their equipment and waited for them to come pick it all up - as I'd repeatedly informed them to do in writing.

They informed me (surprise, surprise) that their prices had increased, and they debited me the new amount for another month.

* NOVEMBER '25:
They debited the R899 clawback fee (which strangely enough had VAT added to the amount... makes you wonder, right?

A 'clawback' isn't a service or a product - it's a penalty, so why the VAT?).

Even though I had previously made various queries in regards to this fiasco, each of them had been labelled 'closed' without anyone actually responding to me.

I have since emailed them numerous times asking them where I can drop their equipment off locally - I'm still waiting for their reply.

DON'T USE THIS COMPANY, AND IF YOU'RE A REGULAR MTN USER (LIKE I WAS), CONSIDER CHANGING PROVIDERS.

DON'T TRUST THE MTN SNAKE HEAD.
If they allow their subsidiaries to operate in grey areas, then they obviously do too.

They don't even deserve the 1 star I was forced to provide just to write this review.

Absolutely Unacceptable Service – 9 Days Without Internet!

I have had the most appalling experience with Supersonic’s fibre-to-the-home service. My internet has been down for over 8 days, and despite logging multiple service requests and calling in every single day, I have received zero updates or feedback.
I spoke to several representatives, including Nelson, Thandeka, a supervisor named Tshepo, and a call centre agent Nelisiwe—yet after 9 days, my issue remains unresolved. The level of incompetence and lack of urgency is shocking.
To make matters worse, every time I call, I wait over 30 minutes just to speak to someone, only to be told they’ll “escalate” the issue. Nothing happens. No follow-up, no communication, no resolution.
This is disgusting customer service and completely unacceptable for a company providing essential connectivity. Supersonic has failed on every level—technical support, communication, and customer care.
Avoid Supersonic at all costs if you value reliability and service!

Bad routers, bad customer service

Had to turn router off and back on so many times just to connect a device. Internet connection is also unreliable, often lost unexpectedly. Customer service via call is totally useless. Had to pay an extra month because they don't allow cancellation within 1 calendar month.

This is the most disgusting service…

This is the most disgusting service provider ever. Lack of service isn't the word. Staff are friendly but are of no use whatsoever. They are merely randoms that answer the phones to tell you you will have to wait 48 to 72 hours for technical support. Don't get this useless service. Rather cut them out and go directly to MTN. If I could this company minus stars they would have minus a billion stars. Terrible business with no service

Shocking service from Supersonic

I have requested on the client zone portal to cancel my Supersonic subscription because of a relocation. I have requested cancellation since the end of July, I have logged multiple tickets on the client zone. there are dates on when
i logged the tickets and how long i am trying to cancel this service. I have followed steps for cancellation. I get a call more than. a month later telling me i need to give more notice until end of Oct.
I get billed for not using your services since Aug and now you forcing me to only cancel end of Oct while ignoring my previous tickets logged on request for cancellation. This is shocking .

You will stop billing me and taking money off my account.

Supersonic, the biggest scammers in 2025

1 star is also too good for Supersonic. They need like a minus number, because that's how bad their service is. I paid for LTE connection and so far I received nothing. I then canceled the order and it's months and I still have not received a refund. Calling them is the biggest waste of time, because a I have yet to meet a more incompetent useless bunch of people. They make government workers look like over achievers. Supersonic is the biggest scammers or 2025.

Supersonic worst ISP - Stay away

Stay away from this company, company sends faulty equipment

Takes money from clients and does not provide a service

When you cancel your service for their error they don't send communication and you will most likely not get a refund

No Internet Since The Beginning of My Contract!

Probably the worst service I have ever received. They gave me an MTN Sim, a TP-Link MR600 router at R519/pm. Ever since I Bought this router I can’t work because there isn’t any internet connection, mind you I paid in full and they make sure that they demand you to pay upfront before they send you their router. It has been 30 days and still no internet connection Supersonic has send me a new invoice to pay again for nothing. This should be considered a crime because their agents called me they promised me to be connected to the internet but yet there isn’t any connection. Not even 1mbps at least!
Supersonic do not know what they’re doing and if you love your business and your money stay away from these people. They will not solve your problems but they will take your money! These technicians are always confused and not well skilled. They only provide generic answers. Please sort out this problem immediately or I am moving to Telkom!
This is horrible I am losing deals and businesses abroad!
