Clearly specify your payment methods

Hi, I have two decoders from Dstv, one is access and the other is compact. On the 8th I paid 130 for my access and today it's been disconnected. I called to find out I was told by Lebo Putu that they took some of the amount and put it on my compact account. I asked why was that because 130 clearly is not the subscription amount for compact they should've known that 130 was for access because it's 129. I then asked for the amount paid torwards compact to be taken for access and was told that they can't do that because the decoders were only disconnected on the 13th. I then asked who gave them the permission to do that because our agreement is from the 7th to the 7th and after that they should disconnect. They said its already been done and I won't be refunded. So my question is why wasn't I given two accounts so I can specify which decoder I'm paying for so that this doesn't happen again? I want my access reconnected. The guy tells me that I should pay 133 so that my access would be reconnected and my question is how would they then know which decoder I'm paying for? Won't the same thing happen where I'll be told that some of the money was taken for the compact? I'm really angry right now because my TV is disconnected and my kids cannot watch and I hane no money.
