Incompetence of dstv customer service centre

I have been a loyal customer of multichoice(DSTV) for a very long time i can estimate more that 5/6 years. since last year June I have been struggling with the incompetence of dstv agents and the supervisors. there is Netflix account which is linked to my dstv account which is unknown to me and im getting billed for this account for past 1 and half years, I have had multiply contact with dstv agent without assistant till today, everytime I contact them the agent seem clueless of what im complaining about and they also say the matter will be escalated. I'm thinking the best option now its to just cancel this dstv products all together. recently I was told by the agent to subtract the Netflix subscription when im paying the dstv premium, yesterday(11 sept. ) I received a call from MBD attorneys saying my dstv account has been handed over to them cause im owing R399 like really
