WORST SERVICE FROM MULTICHOICE

I have had DSTV for over 10 years but have received the worst kind of service for the past 3 months. I have called them to cancel a package that I do not know of and have no existing decoder for without success. Last month I had to pay extra to have such cancelled again, but all was short-lived. After payment again for the current month they suspended the services again and I had to pay double to have the services reinstated and cancel the same package again. I don't understand because i have been paying upfront and if not paid they would suspend the services till payment is made. How do you pay upfront for something you have been asking for it to be cancelled for 3 months in a row and you are not going to use. And the personnel service was the worst. They have lost another customer.
