Jesse.... You didn't miss much. This is a stupid scam call saying that the IRS is suing you for some past misdeed. Variations include saying that you need to pay up NOW or you'll be arrested w/in two hours. ETC!!!
I had a message to call 253-843-6853 saying it was the IRS and that this was their final call before filling a lawsuit. I knew it eras a scam but sanded the number in order to report them to someone. Not sure who to notify, though!
