Knew my name and said he was from the Department of Treasury. I believe it is illegal to pose as a government agency.

FedUp is reporting 202-864-1158:

This morning at 8:20AM a computer-generated female voice left this message on my answering machine: “Hello. We have been trying to reach you. This call is officially final notice from IRS Internal Revenue Services. The reason of this call is to inform you that IRS is filing lawsuit against you. To get more information about this case file please call immediately on our department number 202-864-1158. I repeat 202-864-1158. Thank you.” I suspect that the call will be repeated ate least once more today. I received the same message with a different phone number on 10/9 and twice on 10/21. I've also received similar calls from "Officer Leeza Albrook [or Albert]" on 8/25, 8/26, 9/4 and three times on 9/4 from "Steve Modern", actual human voices who sound like they're either prerecorded or reading from a script. The callback numbers they've left are: 202-241-2794 202-750-0280 936-650-2330 202-864-1298 202-864-1321 202-864-1158 I always Google unknown numbers and found that they're all scams so I've never called any of them back. I've reported all the calls to TIGTA (who have a big red button on their web page for reporting IRS scam calls) and to the FTC, but they're still coming. Grrrrr.
