Denied for a Mortgage

I didn't really expect to get approved, just wishful thinking. The thing is this. When I got the refusal letter, it told me this:

Our credit decision was based in whole or in part in the information obtained from an affiliate or from an outside source other than a consumer reporting agency. Under the Fair Credit Reporting Act, you have the right to make a written request, no later than 60 days after you receive this notice, for the discolsure of the nature of this information.

Name: INFO1
Street Address: 20929 Ventura Blvd #203
City, State, Zip: Woodland Hills, CA 91364
Telephone: (800) 487-4887


I looked them up and INFO1 is a provider of Residential Mortgage Credit Reports and Merged Credit Reports.

Now since I was denied credit because of something this company supplied, does that mean that I can write them and demand that they provide me with the entire file they have and supplied to my potential mortgage broker? Or since it's some kind of a tri-merged report that just has the data from the big three am I out of luck?

Thanks,
