Similar experience as others here. 360-807-5520 left a message saying the IRS was filing a law suit against "You".
For those who don't know, the IRS would never leave a blind message like this. SCAM! SCAM! SCAM!
I just got a call from this number too and went straight to google the number and there it was, a scam. What a bunch of losers. These people need to get a real job!!!
