Same old IRS Treasury Agent scam. East Asian accent. Called him some things that I will not repeat here and he abruptly hung up. This number is an Austin Tx. exchange.

"Hi this message is intended to contact you. My name is Kevin Mason and I'm calling regarding an enforcement action. Executed by US treasury sending your serious attention. Ignoring this will be an intentional attempt to avoid an issue appearance before a magistrate judge or a grand jewelry for a federal criminal offense. My number is 512-994-3524. I repeat 5-129-943-5245 wife you to cooperate with us and help us to help you. Thank you."

This as most of us know is a total fake.

Same here... Reported it to:
