Appalling level of service

The level of service from dstv is so disgusting. I received a call during the month of October offering me a price lock plan for dstv explora ultra which I fell for it as it was a good plan for me. I accepted the offer and it was installed on the 27/10/21 and it has been working fine with no issues until Wednesday, 24/11/2021. Issue was some of the programs were moved from normal catch up to showmax. I have called dstv on numerous occassion asking them to fix the issue as I could not access those programs without data connection and they took me from pillar to post. I called again on the 26/11/21, I was informed to go to a walk in centre near me where the decoder was rebooted. Now I cannot watch 2 tv's simultaneously, it gives me E42 error and I am being informed that I have to get the accredited installer at my own expense whilst the installation is not even a month old. I requested the consultant to take me to cancellation department. I have been holding now for 56 minutes and I am using my own airtime for something that is not working for me. Their service is so bad and products are not convenient for us. When you call again, they don't answer your call
