Blacklisted after contract expire

My MTN contract expired on 29 May 2014, mtn continued deducting money from my account. I called the consultant a month later to enquire about the deduction. The consultant said I made an upgrade which I never did. <br> <br> I told them I never upgraded and asked them to terminate the contract which was for 24 months agreed but now was on 26 months. <br> <br> On January 2015 I went to do financial transaction at a bank and was told that I was blacklisted by MTN. upon investigation I was blacklisted on September 2014. I tried to enquire at mtn but as usual consultants took me up and down without solving problems. Every consultant I met told me the complaint was never captured and their stories made no sense as they kept sending emails to someone somewhere. <br> <br> I want my name removed from ITC blacklist as I paid my 24 months contract without skipping any payment. Mtn blacklisted me for an upgrade which I never agreed to and never received .<br> <br> I filled a report with TransunionReport but mtn never honored it ref TU***<br> <br> Campuscan has the blacklist and experian SA ALSO<br> <br> PLEASE SORT OUT
