I just went three rounds with them and have mailing address and email address - in my file at office - would be glad to get back to you with it on mon am if you can wait that long - not sure if I have a fax # in there or not -
I did find some info here - off my equifax report - FMCC 12110 Emmet Omaha, NE 68164 800-727-7000 at least maybe they can give you further info at the 800 number -
