What a waste , I was called by an MTN agent to assist in getting the fiber on the 9th of January which was a package for R559pm I don't know how or where they got the R1299pm package however that's what I was given, I have called , emailed lodged multiple tickets even made contact with MTN and still no one can get the call recording of the correct package I ordered this is the worst experience ever as I write this I've been on hold for 30 minutes and I'm not hanging up until I get the consultant next thing they will try to hand me over to the lawyers just because I refuse to pay for something I did not ask I wonder why is this company still operating this is day light robery and we as their customers are never gonna be protected I am canceling my subscription

If I could rate Supersonic a 0 star, I would. Their level of incompetence is astonishing. They have no idea what they’re doing, routinely gaslight customers with valid concerns, close support tickets without resolving issues, and ignore all customer communications via telephone, email, and their ticketing system.

I have used several ISPs here in South Africa, and nothing compares to the stress and inconvenience Supersonic has caused me. Their internal mishandling of customer information has even led to accounts being sent to collections unlawfully. I find it unbelievable that a company with over 400 one-star reviews is allowed to operate without any apparent consequence.

This is, without doubt, the worst and most inconvenient ISP I have ever encountered. Their customer service is practically nonexistent. The billing department arbitrarily charges incorrect amounts—even unauthorized ones—and never takes accountability. When you call, you’re left on hold for minutes or even hours with no resolution in sight. Management fails to escalate issues when requested, and when they do respond after a long delay, it is with generic, unhelpful answers that never address the concerns of paying customers.

In summary, Supersonic’s overall performance and service delivery are utterly unacceptable.

Worst service ever. I pay for a 100 Mbps upload and download line but it acceptable for them to get average 20 to 40 Mbps. Tried laying a complaint and was on hold for 47 minutes with no answer. I decided to move to another isp and terminated via the portal. The termination department contracted me once and sent a sms that they could not reach me and I need to request a call back via Whatsapp. Sent request but it does not get answered and after a while gets closed.

Worst service ever the fibre has no internet connection all the time no one answers phone calls no service you pay for nothing I'm stuck wth fibre wth no internet

This Co is a joke it has no proper communication or what soever, the internet just goes off anytime it's wants when I contact support on what's up, what's up is under maintenance soon as it runs out of data I'm canceling it I'm tired of reseting and unplugging it does not work.

Super sonic customer care call center nobody answer your call I had to wait for 50 munits holding on and listen to the computer answer machine

Absolutely useless, we have no internet fibre connection since December. The refuse to send out a technician. All they do is ask you to unplug and reset the router which doe's nothing. Those technicians avoid work at every chance. So I cancelled the account today.

Bought a data package via Supersonic. Router needs to be reset continuously despite good signal. Not supported after 20h00. Operators cannot fix the problem other than through a re-set. They are rude and simply cut you off after you have held for an excess of 30 min.

Absolutely no communication. Placed order and payment before Christmas 2024. No router delivered and after countless attempts to contact them, still answer. Tried Facebook messenger, Twitter, phone calls and emails. Nothing. Trying to get out of this contract and get my refund. Also nothing happening when you log in to their website.

When deciding to get Supersonic Fibre I thought maybe the one star reviews were just because of support, and not because of the internet, but I was so wrong. The fibre ran great for the first month or two, then the fibre just got worse from there. Download speeds are horrible. We were promised that multiple people can download things at once and the speed wouldn't be impacted. False. We were also promised that if many people were using the network it wouldn't go slow. Also false. I play an online game on my computer, then try to download something at the same time and the speed is horrible. Apart from that, when playing games (if you plan on using this for gaming) the loading speeds are pretty good, yet you will disconnect often. I can't run games for more than half an hour sometimes, though at night the problem seems to be fixed. Mainly, the game I'm talking about is Roblox, a game that requires a constant connection to the internet. Horrible Fibre and fake promises. I've been dealing with this for months.

I have been making use of Supersonic LTE since 2022. We have recently looked at upgrading. I logged a ticket on my profile. I received no response for 2 days. I tried calling their call centre numbers and waited a total of 20 mins over 3 calls without getting through to someone. I still haven't received any feedback. Our internet is also currently not working- we thought we ran out of data but we still have left. I then decided to cancel my account due to lack of communication and bad service, however, I have still not received any confirmation from them. Once again, I cannot get hold of anyone at Supersonic, that can assist me and I WILL NOT pay for a service I am unable to make use of.

THE WORST INTERNET SERVICE PROVIDER IN SOUTH AFRICA. This company is the worst, their consultants do not know how to solve issues when you call. All they ask is for you to switch off and on your devices then say they are escalating someone will call back and that someone never calls you. All they want to do is collect monies and not offer services. Absolute nightmare. Run for the hills!! DO NOT USE THEM!! I REPEAT DO NOT USE THEM.

I was with Supersonic from April 2021 with LTE.I switched to Air Fibre in June 2022.I subscribed for the 100 Mbps. It was all good till the first quarter of 2024.It went downhill from there. Slow speeds on none at all for weeks. It's like a ghost company, they dont answer when you call or respond to emails. I cancelled on the 28th of November 2024 with the one month notice period being December, it was acknowledged via email and a call on the 19th of December. Astoundingly, they attempted to debit my account on the 8th of January. I stopped the payment. I emailed and called. No Response. The nightmare continues. Supersonic is owned by MTN.I also had a nasty experience with them about a decade ago. Do not use this company. RUN as fast as you can to their competitors.

I am deeply frustrated to learn that my neighbor, also a Supersonic customer, is paying significantly less than I am for faster internet speeds. While I have been paying R1099, my neighbor is paying under R800 for better service. We tested and confirmed this discrepancy.

I have sent numerous emails dating back December 6th, 11, & 17th... I have also made phone calls, sent to the whatsapp number with absolutely no response.

This blatant inconsistency in both customer care & in pricing raises serious concerns about your business practices. It feels not only unfair but potentially fraudulent, and I expect an immediate resolution.

Please don’t do yourself an injustice by using this company. I had a contract with them that I intended to fulfill, but they promised reliable connectivity while constantly leaving you without internet access. Their customer support is nonexistent; you will never reach them by phone or email.

I paid a prorated fee along with my monthly fee on the 15th. When I canceled my service, I paid the cancellation fee in addition to my monthly fee, yet I was disconnected on the 1st of the following month. This meant I paid the full price for only half a month of service.

I had previously been with MTN but switched to Supersonic, not realizing it is essentially MTN, only to experience even worse service.

I have been with Supersonic since the very beginning but I will not be making use of your services anymore . Horrible customer service! I can never get hold of them and when when I do they do not respond. The WORST ever!

Absolutely CRAP SERVICE.. Cannot get hold of technical support... Takes ages on the phone. Sends email to say ticket is closed , although they did nothing... Cannot connect to the 5g supersonic network. Paying for Fibre that I am not receiving.

They cut my network on the claims that three months ago l had an arrear. You try to reach them to give your proof of payments to show that you have never skipped payments but they are out of reach. The calls are never answered. All they want is money for the service they have not rendered. This is the most awful service provider ever.

This service is very bad.
I called 086 178 7377 for assistance with the wifi speed on the 17th of November 2024, so the lady who answered me let me do 3 speed test and then she logged a ticket SST 521 827 for me at technical SUPPORT. So I waited for them to call me back. Now it is the 20th November and they haven't given me any feedback so I called the number again 2 times and no one answered!

Supersonic is the worst.
They have no customer support, non of the contract numbers are working they just leave in dark no one wil reply ever
