I just received a call today (on my answering machine). Said it was the Fraud Department of the IRS and that there was tax fraud against my name, and call soon to avoid a warrant for my arrest.
I just got through using the call back function on the phone, i.e. not manually dialing. Indian accent, maybe the same guy, maybe not. He answered saying "Ignore the call and don't call back." Then he insisted that I had a wrong number. After I insisted that it was the number from which I was called he hung up. I have a feeling that he is a victim of an ugly prank, just as we are.
Got the same scam message on my phone in California. Indian accent, claiming to be Jason O'Conner from the IRS Tax Audit Department threatening a warrant will be issued for my arrest for tax fraud. Its nice to be able to trace these calls and report them to the proper authorities.
