‪844 364-3889‬ is a liar

By the US Treasury intending your serious attention ignoring. This will be an intentional second attempt to avoid initial appearance before a Magistrate Judge or a grand jury for a federal criminal offense. This is the first attempt to reach you. To resolve this issue immediately and to speak to a federal agent call back number 844-364-3889. I repeat 844-364-3898. Thank you.

I'll wait for the feds to show up. That's what they'd do, they wouldn't call you and leave such a message.

If I knew Chinese, I'd call them back.

Or better, call them back, and say what they said to my voicemail.
