Recently, I disputed item XXXX XXXX XXXX XXXX / XXXX on my report from Trans Union . This is an unsubstantiated account for the reason that XXXX XXXX has failed to provide details regarding their compliance with the law. This letter was dated XXXX XXXX, 2015 and received by XXXX XXXX on XXXX XXXX ( copy attached ). XXXX XXXX failed to provide evidence of their compliance of required proper notices and disclosures regarding the deficiency balance claimed. Trans Union was provided this information in my follow up dispute. Despite this, Trans Union continues to verify that the information is accurate. Attempting to figure out how Trans Union was able to do this, I made a request pursuant to FCRA Section 611 ( a ) ( 7 ) requesting that Trans Union describe their methodology in order to determine that XXXX XXXX has complied with the law. The letter to Trans Union was dated XXXX XXXX, 2015 and received by Trans Union on XXXX XXXX, 2015 ( copy attached ). On or about XXXX XXXX, 2015, Trans Union replied to my inquiry, yet completely failed to address the FCRA 611 per my request. I am requesting from Trans Union that they provide me details of their method of verification including the name and address of the organization or individual providing this information as well as evidence that my correspondence was reviewed by Trans Union and in fact forwarded to XXXX XXXX XXXX / XXXX.
