Embarrassed by DSTV's terrible business practices and service

I have been struggling for six months to get DSTV to stop charging me for Showmax as it is supposed to be included in my Premium Subscription. They have been charging me since they announced that it was going to become free of charge.

I am also not receiving DSTV statements and Invoices, and as I have again contacted them this morning after they have disconnected me, it is evident that they expect me to prove that they have charged me. I run a guests house and am receiving guests tomorrow who booked with DSTV. Although they acknowledge that they have erroneously charged me on occasion, they refuse to assist me in crediting my account before I Pay the full amount.

To summarize: I discovered six months ago that DSTV was charging me incorrectly for a free service. They have disconnected my service claiming I owe them money, without me receiving any notice or warning about that fact. They are refusing to assist me in this matter and expect proof from my side and insist that they are sending me statements and invoices, despite me telling them that I don't. Over the years I have found DSTV's customer services to be **********, the personnel, although always eager to help, poorly trained and never prepared or empowered to assist. I have been repeatedly embarrassed by Them unexpectedly disconnecting my service without any warning, thus rendering me unable to render the expected service to my customers.
