MTN doesnt give me proper feed back

Hi I have a problem with MTN, I wanted to open an account with them for a contract phone and it was declined because im told that I have a previous account with them that I do not pay, I have never in my life had an account and the first time when I want to have one im told I owe a big amount of money, clearly someone *****ed all of this, now my problem is that when I call MTN no one seems to help ,im told to call different departments, ive even sent my affidavit and ID for them to look into this account but im not getting feedback from them.<br> all I wanted was a contract phone but now I have to go through all of this?<br> please help.
