Poor service

I logged a call with the disputes department on 23/08/2017 regarding my credit status as I was advised that an account with Fochini was not updated with Transunion. I spoke to a call centre agent this morning and was advised that they do not do any follow ups to find out why was my account not closed and updated with transunion. Which company does not do follow ups when a query was lodged? I call again 15 minutes later to speak to a team leader and was advised that they all in a meeting, how convenient. I am trying to apply for credit and due to the lack of service from Consumer friend, Fochini and Transunion I am not able to do so. I have proof that my account was paid up in full and my credit report also shows that there is a NIL balance but still that DR interest amount is not cleared according to the credit bureau. I am totally disgusted at the kind of service that transunion is providing.
