"Any information used to validate this transfer is also covered under the FCRA and the FCRA requires the source of any unfavorable information collected to be revealed to the person attempting "credit"."
Western union is NOT a bank or financial institution. I don't see anything in your report to indicate that they even used a "credit report", let alone saw anything that was detrimental to you. Your report states that they could not verify some information that you provided them-not the same thing as a denial of credit, job, etc because of a bad credit history.
Actually, folks with bad credit use western union and moneygram all the time, so I fail to understand, based on your report, how they are violating the FCRA. BTW, I provide consumer credit counseling part time (for free- for about 30 years) and consider myself quite knowledgeable on the FDCPA, FCRA, CROA, etc.
What section do you think they violated? If you're correct, you should sue them in District Court.
