Bad service..

I am not happy with the service I have been receiving from Dstv.. A guy called Noelan Naidoo calls me tallying me about the complain I had lodged, I was excited thinking he is going to assist me only to be told that it is my responsibility to have declined the PVR functions when my explora was installed, he had the nerve to tell me to call the installer to request him to pay me back if I did not opt for the PVR function.. He later then told me me he will cancel it.. I was so angry and to him I am a client the consultant who are well educated about the product needs to explain the T&C of the product they sell us, how am I to know the product when I was not advised of it.. I told him I am not happy with his service as he was rude and was putting the blame on me.. He ended up canceling the PVR functions which I still did not confirm to it being canceled I merely asking who needs to advise me abt paying the extra amount.. Seeing it canceled do I get my refund for June and July? Where is the TCF in what the company is doing.. Since Friday the 31/07/2020 I am still waiting for their call even though I doubt they will call as he has canceled the subscription.. I am still not sure if I am on price loct or not.. Who can I escalated this matter to.. Please help
