I can only guess this is a scammer. It was a robocall stating it was the IRS and they were filing a lawsuit against me and wanting me to call this number, which was the same number that called me in the first place. If it was a true call, it would have been a person, not a machine.

Automated Call Stated this was an urgent call. Left no reason to why the call was so urgent. Didn't even say who the call was from. Very suspiscious.
