Got the same fake I.R.S. call that said they were filing a lawsuit and I needed to call them back, I did and I must say I had a ball screwing with this dirtbag! made my day. But really its just another stupid scammer trying to steal your money.
I got the same thing and asked me if I could pay down on it, will accept $500. They were pretty convincing. Told them all i could offer them is my students loan, lol. They agreed to drop it and let it go. Big Scam
