abuse by multichoices

I paid my multichoice. Acccount, at Maponya Mall branch on 03/05/2015.my account number is ***8.from 06/05/2015 my account has been suspended. I called the call Centre then they apologize and switch it on. Two days down the line same thing happens. Until now it's still happening. I called, wrote many emails, faxed but shame I get no help. They just say they are escalating my issue. I never enjoyed my TV this month
