Payment not allocated for 2 months

I have sent through Proof of payment for January in a form of bank statement, till today multichoice is unable to allocate the payment to my account. I paid for February and because they can't allocate the January payment they cutting me off. I will then call in and they will reconnect just for few days and mind you it has been happening like this from 16th January to date. I no longer know what to do. I mean why cut off for Feb because they were able to allocate it? I am so disappointed with their supervisors whom I feel should have sorted this mess by now. Every time I call I get a new person whom I need to explain the same story over again and again and with every call I make I am asked to send the proof which I always do.
