DMC is s***!!!

One star is not what I wanted to give this pathetic company. I am gatvol with DMC. They are still appearing on my credit report and after having asked them to remove themselves from my Transunion profile, they still haven't. Instead of removing themselve, they keep sending me letters of confirmation that my account is paid up. I know my account is paid up!!! I paid it!!! I cannot have DMC appear under accounts as if I have an account with them when they know as much as I do that it's a closed account. They have not updated since last year October after the last payment. I do not want this ****** company on my name please. Someone had better sort this mess out before I go legal. Every other company I've had an account with has removed themselves after payments were done and accounts closed but DMC thinks they are special. I am giving you 7 days to get your ****** self off my credit report otherwise you will have to deal with my lawyer.
