"Got a automated voicemail from this 206-823-3359 earlier today claiming they are the United States Treasury and if I ignore the message it is a criminal offense and their second attempt to contact me. Never got a first attempt, but OK. The voicemail says "Do not disregard this message and do return the call. Now if you do not return the call and I don't hear from your attorney either than the only thing I can do is wish you a good luck as the situation unfolds on you. Good bye." Pretty sure the IRS wouldn't wish anyone "good luck" ever."
