Fed up with dstv

Dstv has been given me problems for the past 3 months regarding my bill and package. I used to be on a premium package and downgraded to family package at the beginning of this year and that is when my nightmare started. I downgraded to family package and they were billing me for compact and everytime i call dstv customer service they correct it but there system keep on reverting me back to compact without my consent and bill me incorrectly. I called them again tonight cause i have a billing error of R1604. I really had enough, the customer service people are helpful but your ****** system is driving me crazy. I musy say the customer service call operators are helpful, except for one lady who started all this mess. If this is not corrected I'm definitely cancelling dstv completely. I'm just sick and tired of all this mess.
