Total unacceptable incompetency from DSTV

My DSTV account is being charged for a service called (showmax) that I am not aware off and DSTV does not assist instead I must keep calling them with my airtime and DSTV is unable to resolve the problem. I have spoke with 2 of their call Centre agents the first guy did not resolve the problem and did not put comments on the system about my problem. The second lady Nonhlanhla she also does not know how to resolve my problem and yet I am the one who is paying for something I am not aware off. Such incompetency is total unacceptable. These monopoly industries are taking advantage of us.
