Supersonic ISP might be the only private business in South Africa that is comparable to the African National Congress government.
Eager to take your money, entirely unwilling to provide any service, and extremely reluctant to communicate clearly.
On 15 March 2024, I signed up for a Supersonic fibre package. I was due to move to a new address on 1 April, and wanted to hit the ground running.
After signing up, I sent Supersonic a technical support ticket with additional information to smooth over the process. In this ticket, I indicated that the owners of the property I am moving to already have fibre, and that I wish to have my fibre installed on the second line. This ticket has never been responded to.
Nonetheless, 20 March, I received my first and only formal communication from Supersonic. In an SMS, they indicated that my ‘address is active with another ISP’ and that I must supply ‘a cancellation letter.’
Having already explained the situation in my ticket from five days prior, I took to WhatsApp (a number they proudly brandish on the SMS and on their website for ‘fast’ communication). Here is the so-called ‘communication’ I have had with Supersonic on WhatsApp since then:

I obviously also lodged another technical support ticket with Supersonic explaining the situation. That ticket has never been responded to.
I also called Supersonic on 22 March, receiving no answer.
On the same day, I lodged a sales support ticket setting an ultimatum for service by 24 March. This ticket was never responded to. No attempts at contact were made.
On 25 March, the day after my ultimatum expired, I emailed their cancellations address – the only email address I could find on their website – attempting to find out how to cancel my Supersonic account without cancelling Vumatel’s installation of the infrastructure (which would need to happen with any ISP I choose). I received no response to this email.
It is now a month after I first signed up with Supersonic ISP, and nothing has happened.
This company needs to be boycotted. The contempt it shows for ordinary customers who seek nothing more than a paid-for service is unacceptable. It is evident online that other customers have also had immense trouble getting Supersonic to provide any service.
Any cease and desist letters and/or summons for defamation are most welcome! This issue deserves the widest possible publicity. If this is how they choose to engage with me – rather than, you know, answering my three tickets, dozens of WhatsApps, or phone calls – so be it.
