Capital Recovery Services Claimed I have debt I already paid off. Nationwide

 Received multiple calls from a local area code in a row and only 1 voicemail stating "I was part of a lawsuit and there would be criminal charges." (My brother, father, and mother also got the same calls and not sure why 2 of them did since they would have never had their number) I called the number they gave me in the voice mail (855-208-5402) back and the woman took my phone number, informed me I had an outstanding debt with an auto loan I had paid off 2 years ago. I tried explaining to her I had paid it off and she got very defensive and told me to fax the charge off notice with in 48 hours or I'll have criminal charges against myself and my mother who was also on the original loan. She kept rambling about the criminal charges and wouldn't give me the fax number and told me to stop interrupting her. I said "u said I need to fax the paper but haven't given me the fax number" she got very pissed because I had raised my voice at this point from frustration. She rattled the fax number off so fast I missed it and she said "u have 48 hrs to fax it to me. If I don't get it we'll see your a*s in criminal court!" (Yelling at me at this point) and then hung up. After composing myself I called back and got someone else named Debra. I asked for the physical address (so I can certify mail the paper for paper trail) and she said they do not have one and gave me the fax number instead.
