OMG!! This happen to me today, yesterday I got a VM and the same, I could be arrested for IRS Fraud. I called today and they "explain the situation" and I told them I have to talked to my ex husband because he is the one who file the Taxes but they say: If you hangup the computer will issue the warrant for your arrest immediately. He didnt want me to hangup. The guy (A guy from India) told me if I wanted to set up a paynment plan and I said NO becuase I still need to talk with My ex. While talking with my ex on the phone they called a couple of more times and they left a VM< I havent had the time yet to hear it, my Ex Google the number because told me it was impossible and found this blog.
I was so scared and thinking where I could sleep tonight.
