I had read about this scam last year, so was aware of it when I received the first set of calls a few months ago. I told the parties I was aware they were involved in an illegal scam (after requesting their street address which one person gave me as in Washington, D.C., and another in the state of Washington), and then made a complaint about them with the real IRS.
I just received another call (from "Jason Smith") advising I was being sued, so I picked up the phone and gave him an ear full about what I thought of him and his fellow callers preying on unsuspecting people and scaring them, and ended the call by saying to Jason, "If you believe in a higher being or God, I can assure you he is not happy with what you are doing.", and then hung up. "Jason" then called back shortly thereafter, and tried to explain to me that God would not be upset with him because he had tried to get a job in Silicone Valley after he graduated college and no one would hire him so he has to work this job to support his parents. He was not happy that I found his explanation unacceptable for justification of what he does; and then said that if I cared about young people I would offer him a job so he did not have to do what he is doing. Again he was not happy with my reply...especially when I asked him how is it he gets up and looks in the mirror every day and tries to assure himself that stealing is justified. Our conversation ended with him cursing at me and hanging up.
To make a complaint regarding the scam the Treasury Dept telephone number is: 800-366-4484 and their website is: www.tigata.gov (click on the red "scam" link) in the upper right corner after reaching the website.
Got a computer call saying they were from the IRS and was filing a lawsuit against me. Asked me to call them back. I suspected it was a scam because the IRS don't do phone calls, so I looked up the phone number. Just as I thought, someone is saying it is a scam.
