fed up with the incompetence

I switched to debit order for convenience, but sometimes they would not debit my account and blame my bank even though the debit order was catered for. Sometime last April they called to offer me insurance which I refused, but they went ahead and did it, till today they still bill it on my account. I never paid for the insurance as I never signed up for it, now my account was suspended cause I supposedly owe them. I called twice to have this resolved but I've been promised to be called back and till today im waiting and my account still suspended. what makes it worse is the dstv outlet they have at Eyethu mall Orange Farm, the consultants there are very useless they never know a thing, they might as well just close down. multi choice needs to understand that they have competition now and some of us don't mind switching.
