XXXX/XXXX/2015 CFPB helped resolve an issue with a credit reporting issue from XXXX XXXX. You provided me with a letter response from XXXX XXXX with accurate information which I sent a mailed dispute and copy of letter to each credit bureauXXXX TransunionXXXX. XXXX corrected the information, however Transunion is refusing to correct the information. They have a copy of the letter, but are still refusing and are stating they need a newer copy of the letter, even though it is dated XXXX/XXXX/15. 
This has severely impacted my ability to refinance my home.as rates are now rising. 
I would like to have this investigated as to why they are refusing to correct an error that has been sufficiently documented it is an error.
