IRS owe them money. When I informed the caller that I work for the IRS as an investigator and wanted to know his bosses name- he hung up rather quickly.
Yep - just got the same call from this number. Very threatening...I'm going to be arrested...then in a thick Indian accent says his name is "Jason Miller"....suuuuuuurrreeee it is Jason...sure it is...once I said "You don't sound like a Jason Miller", he promptly hung up.
