This number called me, left a message that the IRS was suing me. I called back. It was REALLY loud in the background, she gave me a thing about how I owe like $5300 from back taxes, asked me if this was intentional or a mistake. I said that was impossible, I work minimum wage jobs, I think you have the wrong Lauren. She said (very sternly) no you live at (said an address my mom lived at 10 years ago) I said no, I don't live there. She got mad, seriously, said " Well I don't know how we could make a mistake. Thanks anyway, goodbye" and hung up. SCAM!!!!!
