Messing up my credit profile

<p>Earlier this month I took note that MTN handed over an account which was already settled through MBD, this drastically affected my credit score. On the 19th of May 2016 I phoned MTN and spoke to Palesa Ngoepe who advised me to email her my paid up letter which I did, and she advised me that she will then bring it to the attention of the legal department for resolution, on Monday, the 23rd of May I received an email from the legal team stating that they have sent a request to Transunion to clear my name hence the account is paid in full, I immediately rep**** and requested that they send me a paid up letter from MTN confirming that the account is paid up and closed, secondly, I requested for an explanation that led to the account still existing as open with MTN and now only being handed over. I also requested that I be sent a letter of apology for the adverse action put against me, and lastly, I enquired the reason why they will only clear my name with Transunion and not the other credit bureaus, but my email was ignored. I require an urgent reply containing all the information that I am requesting, this cannot be just ignored like this.</p>
