Transunion Blacklist update!!!!!

Worst experience ever. I have been debt free -settled all accounts I was blacklisted for a couple of months now. And Transunion is not taking me off their blacklist. I have sent an email and was directed to call and the website. The call center does not have an option to go through to an agent. The website does not give an option to sign up. Only an option to log in. Not user friendly at all. I am still stuck with a blacklist by them -this is really discouraging. How do credit bureus get our info to blacklist but never get information to automatically take us off the lists when we arr debt free.
