Inefficiency in accounts department

In Aug I activated my account again with Dstv when I installed the explorer. I paid the pro rate amount for Aug and on 30.08.15 I paid R779 for September using ref ***1 which I got when I logged onto my online profile.By the 1st Sep my decoder was disconnected due to none payment, I called the call center and explained that I paid using that reference number, the consultant advised me that it was the incorrect Ref number therefore the money is in unallocated account, I emailed the proof of payments to have the funds transferred to my account.Only the pro rata amount was transferred not the payment made 30.08.15. Every week my decoder gets disconnected for non payment and I have to phone to explain to the consultants that I am not in arrears with my account. I have emailed to numerous agents the details and till today nothing has been sorted. <br> I cant believe that it can take 3 months to try to resolve a simple query, I am highly frustrated with this service on the accounts department side.
