MTN ***** account still not cleared

Perhaps I should start by stating that I have never been an MTN customer but I was blacklisted by their company.<br> <br> A few months ago whilst trying to purchase a house, we realised that my identity had been ******. The identity ***** used my name to open among others an MTN account and she/he has since been blacklisted by MTN.<br> <br> I approached MTN for them to investigate, I did the affidavit and they found out that it was not in fact me who had opened the account. MTN apologised and they promised that this would be fixed the same day. This is now approaching 3 months and they still have not withdrawn that ********** blacklisting from the credit bureaus. <br> <br> This has made life difficult for us as we have this never ending blacklisting by MTN even if they proved that indeed it was not me who was responsible. The consultant even gave me a letter proving that the account was in fact **********. <br> <br> I have since been trying to reach MTN but I am not able to, I am also not able to take another day off work to go and speak to the consultants personally like I did previously. <br> <br> Please help
