Multichoice won't fix my ds TV

On the 1september 2014 I paid R640 as I always do every month for my two decoders(compact). But on the 15th of September one of my decoders was deactivated. I called the call center, they asked for my proof of payment and I emailed it and the lady had a bad attitude when I told her my problem. She didn't help . Later that day I called again then that's when the other person was able to assist ,sent the proof of payment again then it was activated. The next day the other Decoder was deactivated I had to call again the same procedure happened, the other one was activated the other one was not . CASE NUMBER was given to me but still my one of my decoders was deactivated. This has been happening for the whole week now calling and calling I'm really disappointed with the treatment I get from the Multichoice because I paid my account. Now me and my family are not able to enjoy what we paid for and \on time.""""
