Same thing here, robo message from British sounding robot stating I need to call back to resolve issue with US Treasury to avoid arrest. Call comes from Louisiana, same number called me twice in one hour this afternoon. If you look on the US Dept of the Treasury website this exact scam is listed and they encourage all of us to report it. It says to send email to
[email protected] with a description and to include: Exact date and time of the call, caller phone number, your geographic location at the time of the call, description of the communication. If the caller is claiming to be from the IRS they want you to report the exact same information to http://www.treasury.gov/tigta/contact_report_scam.shtml
