Absolutely useless - don’t ever sign up with them.

Most useless ISP in South Africa. Wifi is down for the ENTIRE DAY, with no communication from Supersonic whatsoever. You have to call the call centre just to try find out what’s happening. And when you call the centre they make you wait for over TWO HOURS and then they just drop the phone when you’re next in line. Still no wifi and still no word from this useless, piece of **** company. Don’t ever subscribe to them.
