Update my info Please

I paid my tekkie town account last year June 2023, I also received my paid up letter. I forwarded the paid up letter to the TransUnion via email in order for them to update my info or to clear my name. The problem is that the Transunion wants a letter to be sent by the Easton Berry's collection not by myself (customer), according to the email received today from the Transunion. So I must be sent from pillar to post now that I finished paying. Who actually must assist me on this matter?
