Harassment of wrongful Bill

I took out a cheap contract at MTM just for the phone. For 2year i paid every month my phone bills on time. Now last year my Contract ran out of the 2 years and tried to cancel the agreement. After Struggling to get the cancellations dept and even going in to one of MTN shops, No Success. I managed to stop the payment going of my account i got an mail informing me that MTN didn't receive payment. Final on the 27 March'15(2 months later) I mailed them back and asked MTN customers care to contact me, I want to officially cancel the contract. NO REPLY. 5 April'15 I send mail again to the same email asking them if the require my ID No? NOTHING Again. <br> Now a few months went by and I am starting to receive sms from VVM DEPT COLLECTION Company that I need to pay an outstanding account with MTN. I called the No in the sms and VVM Consultant said that the outstanding amount is Exporting my sim card from Contract to Prepaid. So, that tells me already that MTN acknowledged my Cancellation March'15.<br> From early November I have been getting these sms's from VVM Dept Collection company that \Action are going to be taken against me\" . I ask for feed back and still no Feed back.After calling alot. "
