Owing money after years of being disconnected

I have a complaint. My dstv connection keeps on being disconnected. I have repeatedly called into the office with the same problem. I spoke to Clement the 1st time and he said the amount would be reversed as wrongfully charged. I am fedup with the service from dstv/multichoice. This is the 4th time and actually I am fedup of repeating my story. I had the service disconnected after my daughter moved out and had no tv service (no tv1, 2 3 or Etv) I called the call centre to be connected again and was told of an outstanding amount from a few years ago and explained that I had the service disconnected myself. I spoke to the gentleman at the callcentre who said It was wrongfully charged and he would reverse it I had to pay R20.40 to be connected. I called in to upgrade and paid R106.00. I keep on getting disconnected. now after 2 years I have oustanding monies owing - but never had a call or received an account. they have my email address and contact no. Howcome now suddenly I owe them??
