This call comes from a highly questionable 'collection" agency called First National Collection Bureau. I recieved a letter from them about two weeks ago in my P.O. Box regarding long past hospital debt. that has been closed for six years and left a severe negative mark at all three credit reporting agencies. check Zombie Debts and Collectors. I've been recieving calls simultaneously from 714-495-4807
which traces back to the same company.
