Really bad experience with Supersonic fibre

I app**** for fibre with Supersonic via Vuma and on the 1st Feb it was installed. However this line has not been activated til today 18 Feb. Every day you query and you get told its escalated wait 24 to 48 hours. Now 3 weeks later no sign of activation and no sign of supersonic. As a loyal mtn customer I thought I was making the right decision but please stay away from this ISP. The feedback and customer service you receive is shocking. Now if only someone can actually activate my line or do I need to find an alternate isp for some actual service.
