Worst customer service from billing/escalations department and messenger on Facebook

I am livid right now from the poor and worst service I have received from their customer call centre, emails at proofofpayment department ( escalations) and messenger on Facebook. On the 23 July I received an sms that they would be debiting my account for R1102 on the 25th July. I immediately call them to enquire about this amount cos my subscription is for R505. The response I got was that its because I missed a payment in June which wasn't true. I then sent the my bank statement reflecting a successful debit by multichoice and the was no reversal what so ever reflecting like they claimed to have made by me. After an investigation on their side and going through my bank statement they apologized and admitted that the error was on their side indeed I did make payment so they would be debiting a correct amount. On the 27 July I got a notification again from them that they were suspending my services because they couldn't debit the R1102 due to insufficient funds. I then contacted them again to ask what this was about now because we had already sorted this issue? Only to be told no I owe them R1102. I had already resent all proof and previous conversations but the arrogance and rudeness I've received from messenger by the agents is beyond me. As it is in Last month I was billed for Compact plus when I've signed up for Compact and I only realized this on the 23rd when I was checking why I was charger R1102. The response that I got about the package change is that it's my problem which I was supposed to raise with them then not now.

In short I have been billed incorrectly for different package I didn't signed up for, and been told I missed a payment but nothing reflects as bounced or reversed by me or multichoice. They took my money but claim to have reversed it but it's no where to be sees in my account. I am disappointed and looking at canceling DSTV cos I can't deal with this. I've tried dealing with this as best as I know how and send all proof but I feel stuck and I am angry
