Fed up with DSTV services

Hi I've been having a variety of problems with DSTV and no one can really resolve your problems, what's the use you can't watch DSTV, but at the end of the month you still have to pay, I've been getting a variety of errors with out any proper explanation, on Saturday missed the rugby, because they couldn't connect the decoder I want as the main one, last nigt we couldn't watch television because of a grey screen which the lady also couldn't explain.
