Several automated messages left stating it was the IRS and to please call the number.  Call started out sounding legit but when I started becoming skeptical in my responses to the man who had answered (and identified  himself by name and badge number) this sick pervert  started laughing and making very graphic and filthy comments about the kinds of things he wanted to do to me.  I did report this number to the IRS.  Still can't believe I was dumb enough to call back much less answer some of his questions.
