Dstv Abysmal Service

It is with GREAT reluctance that I even give Dstv a single star!! I am now becoming more than a little fed up with them!!!! About a month ago, via the Dstv mobile app, I changed my package to a cheaper one. I think it was Dstv compact plus. I was "quoted " an amount of R563 as being the revised subscription. This amount was duly paid via debit order (which THEY control) on the 11th February (a few days ago) Today, my service was cut off as they claimed I still owed R421 - which I do not. After many hours on chat to Dstv service personnel my service has been restored and I was told my new subscription for DSTV premium is to be R767. So I gave up trying to reduce my package, said I would stay on Dstv Premium paid R204 being the difference between R563 already paid, and R767. I now look at my account on the DSTV app and it shows an amount due in March of R1151!!! This CANNOT be!!! They need to look at this and sort it out!!! Dstv service is abysmal....
