I did too and I could barely understand the guy.  He was trying to tell me that the IRS is auditing me from the years 2011 - 2015 because there may have been a glitch showing that I didn't pay my taxes.  The minute I asked for his supervisor he hung up.

recorded call, caller not identified, re: lawsuit being filed in my name and to call and get it stopped

Same...caller represented he was IRS and requested my address.  Said I owe $8000 in back taxes, not the case. Block caller.

Got the same thing. It is an IRS imposter scam. I kept calling back after I reported the number to the IRS website. He said he would keep calling me back and called me and all Americans "White monkeys with Black [***]".

Says it's the irs
