DSTV Decoder and Account issue

I recently installed two DSTV Explora Ultra decoders brand new from the box. One of the decoders started generating a "Disk Full" error and became completely unusable. I called the DSTV customer care who then referred me to one of the local installers (Henberg in Three Rivers, Vereeniging). They replaced the decoder as it was under warranty and was able to resume normal viewing. At month end DSTV debited my account with a sum of R2626.01 which led me spoke to a customer care agent on the 4th July 2022. He told me that it looks like a billing error and one of the managers/team leaders would call me to resolve the issue. He further advised that I make no payment until the issue is put to bed and avoid any further billing errors, but have not heard from anyone since. Today is the 8th, my service is disconnected and without TV. I called customer about 30 minutes ago and he also made promises that I suspect will not be fulfilled. I've been a loyal DSTV customers for MANY YEARS and the only time I have an issue this is what DSTV does. Can someone get this thing resolved????
