Who called from 2027548404

When I called the number back there was no answer.

no answer when I called back...was told to call this number right away to reach thomas obrien at IRS

I called the number back, finally got an answer,, told me I was under investigation from the FBI,, then he gave me a case number, his name was Eric Thompson, with badge number BIR219, the investigation was from the IRS,, I laughed at him and told him "he was an F***ing scammer,, he hung up.

I just got the same thing and  I told them this was a scam a get a real job

I had pretty much the same message from a woman who said she had a case number but did not give a case number but I was under investigation on five counts (Counts of what??? lol)  and gave a phone number.  She then repeated herself and said Good Luck!
