A computerized voice that called itself Natasha Brown, an IRS agent insisted that either my lawyer or I should call back at the same number because I am being sued, even gave me a case number. CH76295. They don't know my history of ignoring lawsuits.
No, you should not be worried. Just someone try to extort money from you, by using fear and intimidation. Please read this, https://www.irs.gov/uac/IRS-Urges-Public-to-Stay-Alert-for-Scam-Phone-Calls
This number has also called me today asking for my lawyer or self to call ASAP as if I didn't something along the lines of "call back now or you will be severely punished and wished me the best".. It was a weird number for WA DC and I don't have anything bad on my record.. So it's very creepy both me and my husband have gotten a call from a 202number! His was about taxes though and luckily I googled it! As my fiancé was terrified since we just revived 2 out of 3 returns that were amended so it was VERY emotional and scared us to the point we had taken all met out to make sure no one was freezing accounts:/ anyways I goggled it and found this and other sites with same directive.. Scammers:/ horrible human beings with no soul!
I received a message to return a call immediately to this number regarding a criminal case filed against me. The message referenced a case number and warned if I or my lawyer did not call immediately "there would be consequences" and followed up by saying if ignored the message "good luck". A couple of weeks ago I received a message from the same number regarding pending action from the IRS.
