Mtn LISTED ON EXPERIAN

I had a contract with MTN which was suppose to expire round about May this year.<br> I paid up my account and got confirmation from the consultant the contract will<br> be cancelled. To my surprise they kept on billing me but with no service that is<br> (without receiving any minutes or data). I made contact with them they said they<br> would look into it with no results. I tried calling but you never get through. I've also<br> emailed their customer service department with no results. I still have the email as<br> proof.<br> Today I receive a call from my banker stating that there is an amount of R221.00<br> listed against my name on Experian for Mtn. Needless to say that I run my own<br> business and that being blacklisted would have huge implications on my ability<br> to make an income.<br> Just today I tried two numbers (011) 329 - 8676 and (011) 912 - 3000 which was <br> given to me by their consultants to no avail.<br> I really need this to sorted out ASAP.
