Super horrible service

Supersonic is worst ISP ever. If you are with them you will forever be Super-Frustrated. The support is extremely poor. When you have internet problems you are forever told that the they are escalating the issue, and someone will get back to you. But no one ever get back to you. I literally spend hours phoning them to get update of my problem and still no joy, so I literally waisted money calling them. I also log tickets to speak to a manager or a supervisor hoping that I can get some answers and tickets are enclosed without anyone call back. I decided to leave them, I logged cancellation with a month notice and now I am being charged just over R 2000 as a bonus for horrible experience they provided to me for the last few months. I don’t even understand why they are charging me so much when they didn’t even do the installation, they only provided the router. It is very sad that we can be emotionally and financially abused like this by this companies and there is absolutely nothing I can do about.
