Received a phone call from this number. No voice message left.

Something about a law suit and warrant out for my arrest.

Called and told , it was from IRS. I asked her to shut up and never call again. The reply was "you [***] hole"

Indian woman. She said Susan from the "Federal Investigation Department" - LOL everybody knows there is no such thing (they're trying to make people think they're the FBI). To inform me that a legal case has been filed against my name and my social and physical address is under Federal investigation". I did not recognize the number except that I knew it to be from the worst possible part of suburban Maryland (PG County) so I let it go to my answering machine so I could screen it. I picked up as soon as she said the above and said loud and clear, "Don't call me back again." I doubt it will work.

SCAM.  I received a voice mail with caller ID of (347) 832-7266 from "Eric Wilson" with "Federal Investigation Department" leaving a call back number of (301) 433-4073.
