IRS scammers threatening lawsuit.  I called number back and they again identified them selves as IRS.  When I asked the heavily Hispanic person for their address so I could bring the alleged money due, directly to them, he answered, "California". Then he offered to send someone to my house.  Gosh, how stupid do these scammers think we are?  I also filled a complaint withe the Do Not Call List as well as the IRS Fraud list
