Threatening phone calls at home & work. Guy with a foreign scent saying they are taking legal action.

i got a call saying that i owed money to a fastcash pay day and this guy saids that i need to send the money right away.

Then what happened?

Threatening voicemail for an employee under me. Foreign accent. Says our employee must call immediately or face legal consequences.

This guy called claiming to be a debt collector on behalf of Fast Bucks payday loan.  Foreign accent, very hard to understand, refused to put a supervisor on.  Debt supposedly 6 or 7 years old, but they hav yet to send me anything in writing,  This same person called me many times after that, leaving very threateniung messages and harrassing me.  Said would sue me, file criminal charges, and have me arrested.  I am reporting this to everyone I can think of.  I tried to call back to get a supervisor, and got the same "gentleman  he also tried to get my social security number and other private information, which I refused to do.  He also left a threatening message on my supervisors phone for me.  I would like to lock this company and their representativer up and throw away the key.  I think it is a total scam, but people should not be able to treat other people this way.
