Charged for Showmax on DSTV Premium Again

I am a DSTV premium subscriber and I am supposed to be getting Showmax for free but every second month I get charged for it and I have to keep calling in to the call centre to get it fixedand then it keeps happening again. I have lost count of how many times this happens and I am getting sick and tired!!! Please Multichoice can you help prevent this from happening once and for all. The agents keep wasting my time and don't actually help me by asking a lot of questions about my account. This other agent kept asking me about my Showmax account and if I can play videos on it but that was not my query! I had to explain my query again to him.

Is there a way to stop this once and for all as I don't want to keep having to call every time for this nonsense. Please!!!
