this man from this number keeps calling me saying i received a 400.00 loan from some company and that the company filed a complaint against my social security number i told them not to call me again

Same message as above

calling and harrassing me @ home, work. I have no idea what it is about.

I don't even know who this is calling me. I couldn't understand him due to his accent. I am not calling him back because it could be a scam. What do I do?

This number called me on the 30th. I called today and they provided me my case number saying I owed $300 to a loan cmpy . I tried to get more information and the first guy, thomas mazear got very rude & direct and hung up on me. Then he put his "supervisor" on the phone. He threating to sue me for $3000, called me a stupid bytch and hung up. He said they are "hardison law firm" but I goggled them and they don't exsist in los angeles, ca (thats the fake info they gave me)
