Same, reported. Robo-call saying to, "Regard this as a final notice" of my IRS debt and that the IRS would be pursuing a lawsuit against me if I didn't call back right away.
I got a call from that number. I guy with bad english gave his name as Office Watson with a 7 digit badge number. He said there was a warrant out for my arrest from the IRS.
Called saying there was a warrant out for arrest for not paying Federal taxes. Was very rude and told me to stop talking while he told me the details. Wouldn't give out number to call back, but finally did. Called him out on the fact he was not the IRS he got mad and told me " F### you" and hung up on me. Call back number and they answer IRS. Total Scam.
