Multichoice is ripping us off.

Multichoice call centre staff is *********** and have no idea what they are doing. I completed a change of ownership form for my decoder and received confirmation via email that it was successful. I made payment but still can not access the channels because of some error code displayed on the screen. I made 3 calls to try get this sorted but no one seems to know what to do. Now I have paid for a product that I can not use. That is a *******.
