supersonic Reviews 

Good day

Please can someone assist me with my wi-fi.

I have been struggling to get reconnected again.
Every time another story.
Every other time there is no one to assist me, because that person is on a tea break.

I have been struggling for more than a week...
I have paid my reconnected on 4/09/2026.

And ever since I have been waiting.
There is no installation nessasary, because I have everything.

I just need to activate the account.
Why is this happening?
Why is this taking so long?

I truly don't understand the problem.

And it is costing me money, ekstra money. Buying data from MTN to do my work!
No one is going to repay me for that!!!
No one is going to pay me back the money I have spend calling to follow up and asking for help.

And then there is a complaint email address to. Where I did leave my complaint. Just by receiving a mail back, saying they do not handle it from there..
Really!!!!

Please assist me. I am really not happy with this service.

Please contact me urgently.

Regards
Veronique

Supersonic is meant to be a company that keeps you connected in order to be able to communicate. Yet, they do not answer Whatsapp, telephone, emails, internet tickets. I have been holding on for over 2 hours. Accounts does not send Statement advising if an account is arrears, they just cut you off with no forewarning. Then, once paid, to get reconnected is impossible as you can't contact them.

The Air Fibre is a scam ,dont try it. It is just a waiste of money and your time. Lack of customer service.

Hi to all if you thinking of moving over to SUPERSONIC for your fibre network think twice im struckling since APRIL 2026 and its September 2026 problem stil not sorted and all it needs is the lan cable thats faulty but just promises everyday.

My WiFi has been down and all they say is it’s with the technicians… I work from home so this is costing me a lot!!!!

Worst service ever.Im currently without wifi for over 2 weeks.
Everyday they say its escalated and everyday the technician is coming out to see whats the problems.Even their installation of the Air Fibre had alot of issues

⚠️ Thinking of getting MTN Air Fibre? Do yourself a favour and check the Supersonic reviews first.

The contract is actually with Supersonic, not MTN. MTN is essentially the network provider behind it.

My experience? 9 days without service, with the response basically being: “There’s an outage, please be patient.”

Just do your homework before signing that contract. 👀
Because you will be let down at some point and not even MTN can help you

Pathetic service. I've had their service for over a year now I'm moving home. Due to very bad circumstances. I've been trying to reach them from the 31 July till today no answer. When someone picked up they transferred me I tried to cancel online they want a one month notice and want me to pay for 1 extra month when I wont be at the property

Absolutely sucks downgraded then got billed correctly next month billed for upgrade back to high ,paid then disconnected for non paid 2 days after payment phone customer support which is non existent A ticket opened the received Email ticket resolved amazing no one contact you.So they just closing tickets without resolving it You then have to open another ticket Opened 3 tickets all identical all apparently resolved nothing happened

I would strongly advise anyone considering MTN/Supersonic Air Fibre to think twice before signing up.

My experience has been one of the worst customer service experiences I have ever encountered. For months, I dealt with recurring technical faults, slow internet speeds, incomplete installations, poor communication, and a complete lack of accountability. Despite logging numerous support tickets, the same problems continued to resurface, and many were never properly resolved.

The following tickets demonstrate the ongoing pattern of poor service:

SST1314450 – Slow speeds (28 May 2026)
SST1315798 – Installation not completed
SST1324019 – Previous tickets not resolved (8 June 2026)
SST1332596 – Connection issues (18 June 2026)
SST1339030 – P1 Air Fibre Line Release / MTN Request REQ000006787052 (25 June 2026)
SST1357180 – Cancellation request (17 July 2026)
SST1359918 – Please invoice cancellation fee only (21 July 2026)
SST1360120 – Cancellation fee and equipment collection (21 July 2026)
SST1364833 – Slow speeds again (27 July 2026)
SST1372337 – No feedback from the technical team (4 August 2026)

What makes this experience even more unacceptable is that, despite formally disputing charges on my account, MTN/Supersonic has continued to deduct funds. Instead of investigating and resolving the dispute before processing further debits, money has continued to be taken from my account. This is not only extremely frustrating but demonstrates a complete disregard for fair customer treatment and proper dispute resolution.

I have spent countless hours following up, repeating the same information to different consultants, waiting for updates that never arrived, and chasing a technical team that simply does not communicate. There appears to be little to no coordination between departments, leaving customers to do the work that the company should be doing.

Even cancelling the service became an exhausting process, requiring multiple tickets just to address cancellation fees and equipment collection. No customer should have to fight this hard to receive the service they are paying for—or to stop paying for a service that consistently fails to meet basic expectations.

Reliable internet is an essential service. MTN/Supersonic failed to provide a stable connection, failed to resolve recurring faults within a reasonable timeframe, failed to communicate effectively, and has continued to deduct disputed funds while my complaints remain unresolved.

The volume of unresolved tickets, the repeated failures, the lack of accountability, and the ongoing billing issues paint a clear picture of a company that has failed to put its customers first.

Based on my experience, I cannot recommend MTN/Supersonic to anyone. I hope this review serves as a warning to prospective customers and encourages MTN/Supersonic to seriously improve its technical support, customer service, and billing practices.

The service is horrible I do not wish for anyone to be with them they are terrible

I have been with Supersonic for six years. They were great in the beginning but customer service went down fast and despite this, I stayed loyal until my internet got patchy and after six months of double billing due to an accounting error and bad internet, I changed. To date no refund for the additional money I was charged and I have been charged an additional month's subscription because their client portal doesn't register cancellations and I can't prove that I canceled my subscription :(

I have been struggling with a failing Supersonic Wi-Fi connection for a month, which was clearly the hardware slowly dying. This morning, the router completely short-circuited and threw sparks in my house—a severe electrical fire hazard.When I contacted their WhatsApp support to report this life-threatening safety issue, the agent completely ignored the hazard, refused to give me an escalation reference number, and literally typed "Thank you for contacting supersonic enjoy your day" before closing the chat.I have spent all of my airtime over the past month trying to call them about their broken service and now have no way to reach them. They are leaving a customer stranded with dangerous, burnt hardware. Absolute disgrace and zero regard for human safety.

Been with them since 17th June 2026 - Air Fibre - Told to upgrade by MTN - was using LTE ZERO PROBLEMS - Pathetic service. not working called so many time - Opened so many tickets - no internet - DO NOT EVER CONSIDER USING SUPERSONIC you will be sorry

Pathetic service, stay far away from these idiots.

Very poor customer service. I've called more than 10 times with no answer. This is not the level of support customers should receive.

My fibre line is off since the 26 June. After a couple of complaints still no feedback. Everytime we phone it is a different story. First it was metro fibre problem, today it said it's been cancelled. Monthy payments up to date. If not resolved I need full refund

Worse service supersonic
I applied for your service on the 6th of this month n I have paid already then 2weeks later Im told there is no fiber lining to my place but on youd app when I do coverage its shows that its covered n you guys dud say that there is a fiber line where I stay but now you have canceled my order .told me someone will call me from your sales team that was on friday on the 12 i wrote i wrote them an email itwas on Tuesday 16 or this is how you do business you just take our money and leave us like that.2 weeks later today I only got a call after I have asked my money back then there call and say there are offering me wifi how while there is no coverage
Worse worse worse service for a big company

Horrible experience. Called several times and sent multiple messages to complain about the Wi-Fi not working and nobody came back to for multiple days. I’m very disappointed .

I have been debited wrong after cancellation.Waiting for my money to be paid back since end March 2026.
Superfast to make you a customer but the billing department is super slow when they need to pay back,now it is like i am begging for my own money.
