Supersonic Fibre Stay Away

Beware of Supersonic My line was suspended without any communication whatsoever, after calling them they advised that I was in arrears. Decided that I will cancel my contract and look for a different ISP. I sent through my cancelation and after 3 weeks I was informed that I needed to settle the outstanding months and that there was a clawback fee for about R1000 outstanding. I've settled all outstanding fees but they are not releasing my line. It's almost a week since I settled their invoice and no feedback in terms of when my line will be released. They've got poor customer service, I would have probably stayed if they just informed me what the issue was initially, but I'm definitely not recommending Supersonic after my experience. Stay away
