Said he was with the IRS and that a law suit was being filed and that I should call him back at a different number which I did not understand because he spoke so fast. When I called the number back was told that I owed taxes from 2006 thru 2009 in the amount of $2000.00. that I underpaid the tax. And wanted to settle out of court. I told him he was a scammer and he started yelling profanities. He was yelling at me and I at him, He finally hung up.
