Recorded message from "IRS".  Scam. The only missing was a foreign accent.

Got 2 voicemails today from this number. Obviously a scam. Very annoying.
"...Filing a lawsuit against you. To get more information about this case file please call immediately on our department number 641-275-8953...." (Woman's recorded voice. No foreign accent this time.) Filed complaint with FTC.gov tho' not likely to do any good.

Got a voicemails today from this number. She stated she was calling from the IRS, obviously a scam. Super annoying.
"Threatening to file a lawsuit against you. To get more information about this case file please call IRS immediately on our department number 641-275-8953...." Will file a complaint with FTC

Called...answered. ..no one there

I got the same call really though if the IRS was looking for you they wouldn't go this rought by leaving a voice message on a cell phone not identifying you by your name jus telling you to call a phone number. and the IRS has 800 numbers .
