Guy called. Said he was calling to speak to the owner of the business. I told him the owner wasnt in and asked if i could help him.  He said he was calling about a suit about to be filed against us.  I told him we don't owe the person he mentioned. He doesn't know what he's talking about. When I questioned him about his name, who he was, and what kind of business he was in he was very rude and a smart aleck and became very defensive.  He used a threatening approach.
