Supersonic service

The worst service ever!!!! I moved house, Supersonic installed a router at my new house and did it with a faulty cable, then I logged calls, from since 15 Dec, which they decided to mark as "Resolved,"without notifying me. I called again, holding in that long que's, wasting my airtime, they logged yet another "call". I received messages from Supersonic apologizing, but a month and a half passed, in that they blamed Vuma Tel, so eventually fed up beyond myself, I called Vuma, they came out the same day, and said I have a faulty router, I once again called Supersonic, apparently no case was logged to Vuma from Supersonic like they made me believe, (both Vuma and Ian from Supersonic, confirmed this) and tried to connect me once again from his side, but no avail...yet again another "expidited" call was logged. I'm so sick of this service provider issues I can scream, in the mean time I need yet to make another call to Supersonic account Dept, to tell them not to debit my account, cos I haven't had service for a month and half...really? More airtime, no service...but eager to take your money....
