Bad company offering bad serve

Bad service received from consultants and when requesting for a team leader or manager for escallation they make excuses but fail to assist. I paid for over R900 for two decoders that are in the same house whilst I requested for one decoder to be active and change the active decoder to be primary. They failed to do that and activated two decorders instant of one. After calling over 4 times since September 2021 my query is still not resolved. I called yesterday and I was put through to cancellation department and the consultant confirmed only one decorder is active but I checked on my DSTV app the decorder I requested to be cancelled its still active and the balance due on 31/10/2021 is R1 072, how is that possible for one decorder on compact package. I have spent over R100 airtime and paid more for the errors of *********** agents. I am very angry
