They called again....Same crap....a recorded message on my answering machine.... Same message repeated 4 times. "Dennis Gray" (with a Indian accent) Calling to tell me of an "enforcement action authorized by the US Treasury" ....blah blah blah...Grand Jury, Magistrate, Federal court, Blah blah blah.
SCAM ALERT - THE IRS (and never the US Treasury) will only send you information using US Mail.
Do not fall for this. It is an attempt to get your personal information they will use to commit fraud under your name.
