Don't use them - you will regret it.

Do not use Supersonic. Their support is non existent. I've been down for 2 days with no end in sight. They've basically turned off their call centre (I was on hold for an hour and gave up) so you can only contact them on Whatsapp. The only update they'll give me is that there's an upgrade in the area and many others are affected. No idea of how long it's going to be. Just don't touch them. You will regret it. I only wish there was a zero star rating.
