I called the dude back from an unregistered line. A guy with broken english answered "treasury". In broken english I told him he called my house and I would like more detail but first I needed his treasury ID....he hung up.
Just got a recorded voicemail from this number stating his name is James and caller ID says he is calling from Rockwall, TX. As all the other people have stated, caller makes threats about going to jail if one ignores the call and doesn't call back to 469-314-8112. Total scam.
