Pathetic customer service!

I’ve had problems with the DSTV for more than 3 weeks already! I’ve contacted customer service numerous times and they were unable to assist. The last time I contacted them they said Multichoice changed over to a new software and therefor I’ve been experiencing problems. The red and green light is still displaying on the decoder and the pop up error message that I receive is E143-4. I’m paying monthly subscriptions for something that’s not in working condition. I've sent an email on 1 October and still haven't received a response! This is really pathetic!!!
