Transunion has repeatedly reported that I was late on a mortgage payments to XXXX XXXX XXXX when they were not late payments BUT disputed payments due to multiple TILA violations. The loan transferred to XXXX during the dispute process and then to XXXX XXXX when the loan was successfully modified in XXXX XXXX. The loan was sent back to XXXX in XXXX and they now service the loan. I have repeatedly notified TransUnion to get this right. On XXXX XXXX, XXXX Transunion finally corrected my credit score to a proper XXXX. Inexplicably on XXXX/XXXX/XXXX they dropped it back to XXXX. My XXXX credit score remains correct at XXXX. I called TransUnion to inquire as what could have happened on XXXX for them to drop my score XXXX points. No explanation that was reasonable was given. I have no late payments nor have I opened any new accounts. So I asked what happened between XXXX and XXXX, no answer. I need your help to get the Transunion credit score restored back to the XXXX it was prior to XXXX. Faxing document
