Just happened to me.... So i called the number back. A man answer the phone and I asked what company did I call and he hung up in my face. I called back and he refused to answer the phone. Please be aware that if you receive an automated message from the IRS it is a scam. All IRS correspondence will be in writing
I just recieved a call too! Never even claimed federal taxes yet not even graduated college yet! Smh said he was from US treasury said I had a law suit and warrant for arrest blah blah
