Horrible service from DSTV!!

I have been disconnected for the 4rd time this month today despite me making a full payment on time and using the correct details. I have spoken to 4 of their consultants so far and each time they tell me that the payment has not been allocated as yet. This is really a HUGE inconvenience because I did what I was supposed to do and I cannot be spending so much airtime every 3 days to get myself reconnected. Today I even spoke to a manager who asked me for a proof of payment that my bank does not have. Apparently a lot of customers have called in asking for the same thing and Multichoice does not want to acknowledge the problem on their side
