UNALLOCATED PAYMENT

I paid my account on 31.01.2015 in full with the exact same reference number I have been using for the last 6 years to the multichoice beneficiary loaded. Nothing changed from my side - yet this month Multichoice cannot pick up the payment! My service have been suspended 3 times this month due to incompetence from the accounts side. I suggested if they could not find it to go look in the suspense account or on the bank reconciliation, maybe the payment was allocated incorrectly to another subscriber account. I got an e-mail form Unallocated Escalations confirming the payment has been allocated and this morning my service was suspended AGAIN!!!! Why should I go through the inconvenience if this is clearly a fault on the side of multichoice. Accounts incompetence is causing me inconvenience. I requested to be contacted by manager for confirmation and nothing, JUST SUSPENDED my service again. I insist on an Apology from multichoice as due to the complete lack of ownership of a problem from accounts I have to endure this frustration. PLEASE SORT OUT YOUR INTERNAL PROBLEMS AND STOP MAKING IT MY PROBLEM AND CAUSING INCONVENIENCE!!!
