Based on recent customer reviews, Supersonic is described by customers as a provider where sign-up is easy but post-sale support collapses. Customers consistently report unresolved tickets, billing errors, prolonged outages, and difficulty reaching agents. A handful of named consultants receive praise, but these are exceptions against a backdrop of systemic service failures across billing, communication, network reliability, and installation experiences.

I get a message saying my account is not paid. Supersonic changes my bill every month... That should be the biggest concern already... So I over pay to make sure I don't go into arrears. Now they saying I am in arrears... Can't call the provider where the only option is to WhatsApp were I'm getting the slowest responses. They say they're checking my account where I stupidly have over paid. If you are going to cancel or suspend my account, just know that the made up amount is not going to be paid and I will consider this as you giving me an opportunity to move to another provider.

I placed an order with supersonic on the 11th of May for Wi-Fi at my home , to date I have not received any help. I was told ZOOM fibre is causing a delay however when I contact ZOOM fibre I am told that my order is still in progress with Supersonic. I was promised a call back from a manager named Lerato from supersonic and today again the same broken promise has been made. This is pathetic, This is absolutely terrible customer service. MIND YOU MY DEBIT ORDER IS SCHEDULED FOR THE 1st of the JUNE. Watch them debit me without even fully fulfilling my order. What a joke this ISP is. I even got an sms stating my line is active . LYING to customers is a shame

I recently moved over from RSA Web in April(Thinking it was the worst) to supersonic and my oh my so far it has been the worst experience ever. When Octotel eventually came out to activate my line, I thought my troubles was over, but the issue persisted. In the few weeks I have been with Supersonic, I have called them thrice every week explaining the issues I have with my internet line, and they keep on asking me to do a speed test, which I do, they receive it but never fix anything. A movie is 1h40 mins long and I watch it in 2h30 minutes because the internet keep on connecting and disconnecting. I do not know what to do because having a solid internet line is imperative to me and my job, but this is costing me to pay for a service which I cannot enjoy. On multiple occasions I have called the contact centre and requested to speak to a manager and I am constantly promised a call back, to date I have yet to receive any call from any one at Supersonic!!!!! I want Supersonic to send out a tech to my home and have them check the line, not just a surface check but to connect to my internet and see how often it disconnects. My speed test show how perfectly it runs, but how can it run perfectly if it keeps on disconnecting.. I am thinking of taking matter further and I do not want to if you just come out and fix the issue so that the 619 I pay each month can be worth paying!!!!!!!!!!

I was a customer with Supersonic through a promotion with MTN and I received poor communication from and they never told communicated changes to price or promotions to me neither did they communicate that even though the promotion said "month-to-month" and "cancel anytime" I'd have to pay back a 12 month claw back fee of R899, and now they said the promotion was only for 6 months and due to changes to the pricing which wasn't communicated to me I owe them R1876 suddenly. They never communicated with me and never responded to my emails or whatsapps to them.

I am utterly disappointed with the service provided by this WiFi company. The so-called advisors are completely ***********, with no understanding of the products or services they are meant to support. Their lack of knowledge is shocking and unacceptable. The customer service is ********** — slow, unhelpful, and dismissive. Every interaction feels like a waste of time, and instead of resolving issues, they create more frustration. I would strongly advise anyone considering signing up with this company to think twice. Save yourself the stress and disappointment. This is by far the worst service experience I have ever had, and I cannot recommend them under any circumstances.

Very disappointing customer service experience. Every time I call, the staff sound completely disinterested and unhelpful, as though assisting customers is an inconvenience. A more professional and customer-focused approach would be greatly appreciated.
