DStv complaint

I have been a loyal DStv subscriber for many years and pay my account via debit order. About 2 months ago I upgraded my package from Compact to Compact plus and cancelled the PVR facility and at the end of that month i was downgraded automatically again to Compact and the PVR facility was activated again. My debit order was higher than usual and i figured that it was due to their annual April increase. On Friday 27 May 2022 I got debited R2302 for my Compact package. I called them and spoke to Tebogo Mokoke (who was more helpful than today's consultant) who then said that he could see another active decoder ob the Premium package. I asked him who was in possession of that decoder and who it is linked to and why i am being billed for them. He said that its in my name but looked like it became active due to a system glitch and he would have the extra fee reversed by this morning (30 May 2022). By 15:00 i didnt get any notification about the reversal so i called them again and gave my reference number. They said that they would only reverse R800 because i upgraded my package and that they would investigate why i feel more should be reversed. I cancelled my subscription on the spot and requested that my bank reverse their debit order. I am willing to pay the fee for Compact but not a cent more. These technical glitches and a ****y consultant just cost them a loyal customer
