This situation is strongly suspicious for scam, and almost certainly subject to sanctions in connection with your bankruptcy and and the federal Fair Debt Collection Practices Act. The problem that commonly limits recovery is when the scammers are offshore and beyond the reach of our justice system. To assist any attorney or agency willing to help you, you should gather as much contact information as possible. Record any phone conversation, which is legal because Idaho is a one-party consent state. Report your contacts to your bankruptcy attorney ASAP and, if you have been foolish enough to proceed without counsel, consult with an experienced bankruptcy attorney about legal services to pursue the debt collector.
By the way, debt is a civil matter. Failure to pay is not a crime, and the debt collector is powerless to cause you to be arrested. Pay nothing until you have written proof of the deb, reliable advice and competent legal assistance.
Best wishes for a favorable outcome, and please remember to designate a best answer.

This is being reported by others consumers on AVVO as a growing problem. If you didnt borrow the money, you don't owe anything to them. This is likely a criminal operation. Report it to your state Attorney General. You cannot be arrested for non payment of a debt even if you did owe it.
