A collection agency has contacted us for a whopping $26.20. They had called and provided me a copy of their license number in their state. I called to verify license number and it expired last year. It was non-renewed. I have the letter with envelope postmarked. They have NOT reported to credit bureaus. They are also not licensed in my state. How do I respond to them? The man at the state agency said that if I forwarded the letter to them, it would be a felony (impersonating a licensed entity or semething like that). What would you do next? Thank you.
