Payments not Alloacated

My account has been switched off since the 20th of September 2015, due to non payment. The operator can't tell me for which month so I've forward a whole years proof of payment from Sep 2014. Every 3rd day my account is suspended, then I have to phone in only to hear the same story about outstanding proof of payment.<br> I spoke to a manager on Wednesday 21 Oct *** i18 when I was told that I was charged with all the reconnection fees whilst Multi-choice billing department was clearly *********** to allocate payments. After that call I waited about 10min and phoned back in again to confirm my balance on my account only to find out that nothing was reversed by the previous operator and his manager. With Ref.i19 my account was reversed and wouldn't be suspended again. Monday morning 26Oct my account was suspended again, I phoned in and spoke to the manager Promise that told me that nothing was outstanding on my account and don't know why it was switched off, but they still need proof of payment for unallocated payments. ***?? They don't have anything like customer service and the manager Promise can't deal with a problem, just kept on saying sorry, sorry!
