DSTV Over-billing nightmare ( Services have been disconnected)

I have been calling DSTV for the past 3 months trying to tell them they overbilled me on my account, I was told the money will be reversed into my account after finance approved it and that was in December,

Come January my services were suspended due to that overcharge i got in December, I called again and complained of the same issue, my services were activated and was told that they are fixing it, I visited the walk in center on 9 feb 2019 after my services were suspended again, I was told I dont owe them any money and all the transactions were reversed and again my services were reactivated.

5 days down the line, my services were disconnected again and I phoned a lady and my call just ended and I was too frustrated to call back again to start to explain from scratch to another rep again. I called the following day and was told the same thing that I don't owe them anything and again my services were re-activated and was told my account was going to be sorted out.

Here I am sitting again waiting for my account to be deactivated again for their billing error.

The story of my life thanks to DSTV.
