The other night I received a call from some man from an agency he did not specify, I later called the number to see who it was it was from Regent Assets Management Services. He was looking for me, he had my address, and was talking about a debt I had with U.S. bank about 2-3 years ago. I had settled this with another collections agency and have proof that I paid it off. I got my credit reports today and it says on them that i have 0 collections claims against me. This man on the phone slightly threatened that if I don't get back to them in less than a week they will have their "attorneys" call me. I did not give him any information. I told him I have already taken care of this. What steps do I need to take? I have not received any letters only this one phone call.
