Billing issues not resolved

We have been strugling from November last year to sort out my moms account. After several calls and promises to look into it and came back to us or they will fix the problem. Today they switch off her dstv without the problem been resolved since then. She was payig her account every month. This my third complaint and her billing issue has not been resolved. Within these months she was calling Multichoice after every day with no fail. There response on hellopeter is to just give you false hope! And to shut you up, they never follow through. How do you solve your hellopeter complaints? I would swear you guys work on a piece of paper. Can someone allocate this to a person that can resolve this. Payments was made in time it is not my mother problem if you can not work on your queries and give customer service. Does it really make any business sense to have ongoing queries for 4 months of the same issue. We have given you guys more than enough time. Now the agent is telling my mom she has 2 accounts how is that possible? Does your agents know what they are doing?
