I am bein told that I can have felony charges file

Think about this for a second.  Some stranger calls you up from out of the blue and tells you you're being charged with felony.  Really?

Nope, they cannot do that. Debts are civil, not criminal. Who did you borrow from and what state do you live in?

It is not possible. It is a fabrication of facts. You don't need to believe it. 

Threatening arrest or legal action is prohibited by the FDCPA

Non-payment of debt is not a criminal offense. It’s a civil case. So they can’t file felony charges against you. By the way, what state do you live in? What is the name of the pdl company? Is your lender licensed in your state? If not, then they can’t take any legal action against you.
