Breach of Contract

Once again Mtn are doing as they please. Please check all my previous complaints send through. Long story short, these amounts outstanding on my account is supposed to be reversed and this account closed. From 2 Nov 15 we did not have phones but you keep on billing me, in December I paid my daughters account and you blocked her, after I warned you that if that happen I will not be paying this account. I got her a pre-paid card and since she has not been using this number or contract. You keep on billing (and once again just whatever amount you please). Feb I get charged R169.01, March R220.75 and April R47.26 for Blackberry Internet Service. WHAT ARE YOU DOING? My daughter doesn't even have a Blackberry and how can you just bill whatever you feel like. I have been battling for more than 2 years with Mtn now and I think that I have now had enough of your incompetence. Please reverse these charges and send me a nil balance statement as I will not pay this and will take this matter further should you choose. I have liased with my attorney already. Your breach of contract make my contracts nil and void. And you can check that none of your contracts values and datas have been used.
