Internal Dispute Resolution Fraud Dept. Company threatens you with arrest for supposed bad checks or loans you've never taken out

I was contacted by the number above and told that I had bad checks from 4 years ago from a bank I have never held an account at. I asked to be mailed this information or to be able to verify it and call them back. They refused and told me I was being uncooperative. I informed them I had never even had an account at that bank. They didn't care. They had called once before telling me I had a loan I never paid off. I never took a loan. I told her to go ahead and proceed with having me arrested. She then started geting angry with me at which point I told her to get a real job and stop trying to scam people. She got even more angry and told me they wouldn't even take a payment now and that I had to pay the WHOLE balance. Then she hung up. Just to be safe I called the bank and they ran my social and confirmed that I have NO account or past due balance just as I knew I didn't. Don't give these people any info or money. They are scams
