Account Paid yet Service continues being disconnec

Once again my services is suspended even though my accounted is paid in advance. This has been the fourth suspension for the month and my Multichoice account is inadvance inclusive of a credit. It's costed me over R400 in cellphone calls to them. And my advance payments have been emailed to 2 customer care agents Siyasanga Vitshima and Themba Maseko. I've also emailed both these agents advising them of the continues messages that I've been receiving asking for payment to be made. Yet to date neither of them have responded to my request. And this evening once again. I received the message indicating my account is in arrears and payment needs to be made. And probably by tomorrow morning my service will once again be suspended. Well if that happens Multichoice can cancel my subscription and shove the service. I've been a customer for almost 15 years and this is the worst customer services ever.
