No response from MTN

Dear MTN ,<br> <br> i have tried emailing you on several occasions with an attempt to cancel my contract via the \" email address & have not received any response regarding the query.<br> <br> With my previous contract cancellation it took almost 2 week to get a response.<br> i have not also received any knowledge that my query is been dealt or the receipt there off.<br> <br> calling the call centre number is also a total waste of time as there is no response or the calls get dropped.<br> <br> PLEASE CAN MY CONTRACT BE CANCELLED!"
