I got a few calls from this number claiming to be the IRS saying that it's their last attempt to reach me before taking legal action. It is a totally fake call. I called them back and said that I passed their number on to the police because I know that it's fake. They immediately hung up on me. I call them back again, they picked up, said nothing for about a minute and then hung up without saying hello. They did that two more times until I called them from a different phone line, then they picked up and said hello. When I told him who I was, they hung up again.
