Robo call, some sort of scam. Threatening message saying the "IRS has issued a warrant for my arrest (no name indicated), and is monitoring my property."
I called the number back and talked to Bokato. He is in Delhi and wants to be paid off using Walmart and Target gift cards. After you buy them then you call and read off the numbers. I kind of enjoyed messing with him. He said his bosses name at the IRS is Shaggy.
