Failure to Discontinue Runout Contract

On November 15th 2015 or there about, I called the 808 call center number to request my number be ported to prepaid since I had overran it by a full year and was not looking to get a contract upgrade. It is now January 19th 2016 but my contract has still NOT been cancelled.<br> <br> I went ahead and cancelled my debit order at my own expense. The bill from MTN is STILL accumulating. What is next ? BLACK LISTING ??????
