collection agency, dont erase the recording, call back pretending you want to discuss debt with them and get all their information and contact your attorney. They will settle for $20k every time without contesting you. I know how it works.
The called my aunt in Paand threatened her saying I would be served or arrested for a breach of contract they were cussing at a 75 year old who has severe nervous condition. I live in Virginia and any contracts or loans or debts over past 10 years have been paid off. I have no contracts and my credit score is pretty good, so my guess is scam I remember them doing that 6 years ago called my aunt who is the only one in family in the phone book. That was about a debt that was paid infull in 2004. Scam
