Like the rest of you, mine was a threat from the IRS as a last warning they were filing a law suit against me.  Bring that phony lawsuit on.  I wish there was a better way to stop scam calls.  When they come in on my cell, that's where I draw the line.  My home phone is used strictly for faxes and I never pick up because 9x out of 10 it's calls like this!  Infuriating.
