Bad Customer service

I have been struggling simce November with this company. I pay my dstv subscription on time but they keep disconnecting me because of re-connection fees that they load because they have not allocated my payments. For the month of December they disconnected me 5 times. I keep sending proof of payment. Over ten calls from a pre paid line and a walk in to the Multichoice centre in Goodwood Cape town they still disconnect me everytime. This is the worst customer service ever. On top of it they tell me they cannot give me a mangers contact details. I am totally disgusted with Multichoice.
