Customer service worse than Telkom

Supersonic has the worst customer service from an ISP. It's impossible to have an financial issues sorted without constantly calling to find out if anything has been done to resolve the issue. There's no feedback on matters resulting from their incompetence. I've been charged for subscriptions I did not order or use. Trying to get a credit note for months. When I phone in, all they say is that they are escalating the case, which means absolutely jack if nothing gets done. Signing up with them was the worst mistake I made and will be cancelling as soon as the 6 month cost claw back period is over, fortunately there's just 1 month left.
