Contract wrong and overcharged

This is probably my last chance.<br> My problems started end last year but I finally got my phone working end of February.<br> <br> The contract I signed up for was MY MTNCHOICE100 (use own phone). It should include 100 minutes, 100SMS's and 100MB data. I am not getting the SMS's and DATA.<br> The price quoted was R68.00 & Billing R24.00 & CLIP R8.50 & Sim insure R6.00 . Total of R106.50.<br> <br> I now received a bill for R147.80 and usage of R146 that should have been included.<br> <br> This is a break of the contract and I want to cancel but they dont answer my emails and complaints<br> <br> The last person (a supervisor) named Arnold said he would call back but did not.<br> <br> I need to some manager to CANCEL.<br> <br> Eugene de Villiers<br> ***
