Scammer. I have been calling him back 100's of times each day since he called. He answers saying he is the criminal investigation unit of the IRS and if we don't send him $3000 he will have the police to my home and place of employment. IT IS A TOTAL SCAM AND I WILL NOT STOP HARASSING HIM BACK UNTIL THE LINE IS SHUT DOWN. The guy was ignorant enough to be using his land line. He also has a fax #, 302-361-5754.
