IRS Scam calling about a case number from a wireless phone number.

I've gotten several calls from this number. Each time they leave a message that this is a warning, the IRS is going to sue me, so call back. I call blocked my number and called them an a guy answers "yeah? Gee, just what you'd expect from the IRS. I am so sick of these scammers and I'm so disgusted that our lovely government doesn't do something to stop this harassment. I get at least 10-15 solicitors and scammers everyday on each line I have so that's 20-30 calls I run for only to hear this garbage!

Apparently a wireless caller from the "IRS" is suing us....lol

CID: Wireless Caller. After looking at other sites, I have found this to be another IRS scam. They threaten to sue you to pay back taxes from 2009-14. Fortunately, my phone system automatically blocked this number as a robo caller/scam caller. The IRS never calls threatening anything.
