Multichoice Bad Service

I'm so irritated by Mulchoice, I'm even considering canceling my subscription once and for all. For the past 3 days, I have been calling them every evening regarding my exta-view decoder that lost signal. They get it right for 1 day then I have to call again the following day. To make matters worse I always get rude consultants who make me wait forever on the call, then decide to just cut the call! The decoder is still stuck on Chanel 100 as the lady just cut the call without assisting me. This totally unacceptable as I'm paying for a service that is constantly interrupted!
