Atrocious service! Depressed and Frustrated! Botched Installation!

We got Supersonic to install fibre at our house in July 2020. The installation guys were very quick to come to my house but they did not install everything properly and since July we have not been able to use their service even though we get billed every single month for a service we have no access to. We have called them almost every single week since the botched installation was done. Every single time we are made to wait on the line for more than 30 minutes until we drop the phone and call back and same thing happens. The technicians we speak to are not helpful and tell us that they will escalate the issue and someone senior will call us back but nobody has ever calls us nor have they ever sent out a technician to the house to fix the problem. We are being billed for a service we do not use! We have no Internet and are unable to do anything that requires us to access the Internet because of their incompetence and atrocious service! We want to cancel this installation and get Vodacom fibre instead! We just want nothing to do with MTN Supersonic! We are sick and tired of the bad service they have given us over the last 4 months! We will make sure that this poor service they have given us doesn't go unpunished! It's torture dealing with MTN Supersonic, it's frustrating and depressing!
