DSTV Poor service

I made a mistake when I was making a payment of R400 on the 3 of October 2019 and put "DSTV" instead of my account number, I have been trying to get the money allocated into my account for the past three weeks with no luck, I have been given different emails to send the proof of payment and it was not going through, And they keep on sending me reminder that I am owing R393 yet I have an amount of 400 that they are failing to allocate, I call the customer care everyday and they all tell me the same story. Yesterday the call center lady by the name of Busi told me that she will not assist me if I keep on asking a lot of questions. The exercise of following up my unallocated payment has been nothing but a pain and waste of airtime as I always get the same response with no help. DISSAPOINTED CUTOMER
