In May I disputed my AU account with Transunion because the balance was incorrect. Instead of updating it they deleted it and hasn't showed up back on my credit report. I sent Transunion a letter along with a statement of the account but the only response I got was a credit report. I was wondering if my mom was to ask to let me be a cosigner on the account instead of being a AU to keep the credit bureaus from deleting it when I dispute it? Anyone ever heard of creditors adding co-signers after the account has been opened for sometime? SPELLCHECK** How do I add my AU account back to my credit report?
