Multi-touch complain

I have experienced a bad service from multichoice for the past months I've been calling them to make the payments arrangements from the 25th to the 1st of every month, and the last time I called them I was told that my query it has been resolved. Today my service was stoped. I called in and I have spoken to Sweetness enquiring about disconnection, she told me that for my service to be reinstated I have to pay for the connection fee. I tried to explain to her that I have change the payments date, she insisted on saying I have to pay. Then I realise that she not willing to assist, I asked for the superior, she says she will put me through. I hold the line listening to that annoying music until my R100 airtime was exosted. It seem as if that's how Sweetness is treating the client because she knew that the call is not for free, eventually the airtime will be finished. The worst of all she never had that courtesy of calling me back. If Multichoice can have competitors then they will learn to give their client the best service, and hire people who knows the meaning of customer care. Please assist and thank you in advance.
