I got the same message left on my voice mail from same phone number, caller ID says Blackwood NJ. On my message the caller left his name as "James Caston", he spoke with an accent. I'd say the message was pre-recorded.
Called my home # at 9:15 a.m. on 12/5. Left message. From a 'Stuart Wilson' claiming to be contacting me about 'an important legal action by the US Treasury intending this years attention'... then goes on to say that 'ignoring this will be an intentional 2nd attempt to avoid an issue appearance before a magistrate judge ordered grand jury for a Federal criminal offense'. Then they say they can help me & to call them back. Sounds VERY fishy & scammish to me... I've never had any legal trouble & this is my 1st call from them. Sounds like a 'scare call' to get you to give them personal info...
