Supersonic - Worst Fibre Internet Service Provider

I have not had wifi for the last week. I have phone Supersonic about over 20 times this week and have been on the phone for over 5 hours with no joy. They promise resolution in 24 to 48 hours which is never achieved. They promise to call you back with feedback which is never done. The reason why I moved from Telkom to another service provider was due to their service which I thought was the worst in the country at the time. After dealing with Supersonic I honestly believe they are way worst than Telkom
