Left message about a "case file" - I actually have a case file with the State Dept going so I called back. (mistake) It was a HEAVILY accented person claiming they were IRS. Bullsh*t. Hung up. Reporting them to FCC.
I got a call from this number and heard a recording that claimed it was a final notice from the IRS filing a lawsuit against me and that I needed to call the number right away. It said "Haiti" when I looked at the number. Please report them to the FCC.
