Credit reporting or other personal consumer reports: Incorrect information on your report

I have been disputing an alleged bankruptcy on my TransUnion credit report for over 90 days. Despite my repeated disputes, TransUnion has failed to respond or conduct a proper investigation into this matter. The bankruptcy in question has not been adequately verified as mine, yet it continues to be falsely reported on my credit file. This inaccurate reporting is not only damaging my credit but is also unlawfully preventing me from accessing credit opportunities. I have mailed the same forms of identification and address verification, along with my dispute letter, that I have uploaded through this portal. However, as indicated in the letter I received from them, they are incorrectly claiming that the letter was not sent by me and are questioning the validity of my identification. It is important to note that the forms of ID I provided are exactly the same as those required according to their own website.
