Legal Mediation Practice Threatened to put me in jail if I didn't pay a little over $1000 Jacksonville Florida

I received a phone call from Jim King with Legal Mediation Practice telling me I was going to be picked up and put in jail the next day if I didn't pay a little over $1000. He claimed that I wrote two hot checks from a bank I never heard of (First bank???). He would not provide proof that I wrote the checks. He had the last 4 digits of my social but not the whole thing. I told him I didn't have any money he asked if I had any friends or family that loved me that would pay. This seemed weird so I researched his company and they seem to be full of it - just out to scare people.
