DSTV Off Due To No Response From DSTV

I sent 2 emails asking for my billing date to be changed form the 15th of the month to the 25th as I have changed jobs and pay day is different. No one bothered to email me back or pick up the phone and say it can be done. After hearing nothing I assumed all was in order and I wake up today and my dish is suspended. Terrible customer service once again by multi choice.
