Sabotage

I have paid up my account and home choice do not want to update my status at transunion. I wrote a review 3months and was promised they will get back to me even today. This issue is affecting my employment as i keep receiving emails from HR saying i have a negative credit and as a employee of financial institution is not good. I received paid up letter from their agent and was advised it will be sorted but still hanging. I cannot get hold of home choice on the phone and they do not respond to my emails.
