Poor Pathetic services

According to multichoice their system did a update On the 11 August 2015 and there was a second slimcard connected to my account without my permission. Since then my service was disconnected 5 times, according to them we are in arrears with our payment. I did email the proof of payment as well and still they keep on disconnected my services. The operators admit the fault is on their side. So their mistake cost me more money every time i have to phone them to sort out their problem. When you phone them you must HOLD ON FOR AGES. When you finally get someone to help you they make one promise after the other. My account is still not sorted out and its very clear they don`t know what they are doing.
