This number has called before - I didn't pick up the phone (I won't if I don't recognize the number) - a recorded message of a man with a very thick middle eastern accent asking for someone named "Wanda" and essentially threatening that they need to hear back from "Wanda" or her attorney... "Don't even think about ignoring this message" yadda yadda.  Some of the pronunciation/diction even made me think it was a computer generated voice... very strange.  It creeped me out enough to not call their number back... enough to consider reporting it to the FBI.
