Got two messages today from this number ("wireless caller") of a recording that "IRS is filing lawsuit against you. For more information on matter, call our direct department number 434-851-6625." Yeah right. I'm sure if I call, they'll tell me to wire money immediately (or use Green Dot or some other non-traceable means) to avoid the lawsuit. Nope. First contact by the IRS is ALWAYS via US Postal Service, and you NEVER pay by an untraceable means. (You need proof of payment.)
I'll be reporting this to the IRS fraud line (https://www.treasury.gov/tigta/contact_report_scam.shtml) as well.

And a third call, same number, same scam. If they call you, report it to the real IRS via the treasury.gov link in my previous post.
I received a few similar scam messages from different numbers a year or so ago, and reported them too.

Caller said he was from the IRS, and that this was the last notice of a lawsuit by the IRS.  It was a recorded call.  I called back and spoke with someone with a foreign accent.  His name was unintelligible.  I asked where he was located, and he said 111 Constitution Ave.  I asked who he worked for or represented, and he hung up.  The initial call was received 3 times in two hours.

*Indian Accent*..Did the speaker speak in an Mid-East accent? The call is from India...A very hotbed for scams.

caller ID reads :: DCN :: Did not answer. Don't know who these people are or what they want. Did not leave message.
