I received the same call from this number 3 hours ago. I called back, and an Indian female answered "Treasury Department." I told her she is full of [***] and I hung up.
Didn't recognize number and didn't answer. Fuzzy low quality voicemail by someone who seemed to be trying to disguise an accent saying he was from the treasury department and have to call number back and there would be consequences. Clearly not legitimate.
Scam artist - Name is James Caston - calling regarding US Treasury related issue, and not calling back would be an intentional offence requiring appearance before a Magistrate or a Grand Jury etc.
