Dstv incorrect account amounts

On 26 April i phoned the customer care number to find out what my account is to make the payment and i spoke to Paul Sidibe. He asked me all my details and confirm that i have a credit of R500 and somethind can not remember the excact amount. I asked him several times if he is sure about the credit and he confirm it every time and also said that there is a debit on the pvr account of R52.50 if he may take some of credit and transfer it to the PVR account. We did the transfer. For the month of amay i did not made a payment because the credit of R550 was more than my R360 amount that my subscribtion is costing me every month. The end of May i paid a amount of R200 for the folowing month because again with the credit left if the previous month and the R200 my sybscribtiin would have been paid. On theb13th of may multi choice disconnect my dstv. I phoned them and told them all of the above and they said that there is no credit reflecting on my account and that they must sort out my account. Listen to the recordings and take the reconection fee of from my account because my account are auppose to be up to date. They request a incestication and said they will phone me back in 24 hours. That was a lady by the name Ziyanda. The next day my dstv has been reconect byt they never phoned me back to let me know what the outcome was. On the 27th of june i again went in on my acount to see what i must pay for June and i got the amount of R441.71. I made a payment of R500. 2 days after the payment was made i again looked at my account and again they said i must still pay R300 and something. I need help to sort this issue out and get my account cleared because they do not know what they are doing and i know for a fact i always pay a little bit more than my subscribtion and that Paul confirmend several times that i have a credit of R500 and something and u still made oayments after that in order for my account to be up to date and running.
