That number is a non-working number now. I think they will use a number for a day or two and then use another number. I got a call from that number yesterday. I just called it today and it is not working. I got a call today from a different number and told the guy with a thick foreign accent that I knew this was a scam. I bet if I call that number back in a little while it will not be working either. 765-821-0243
Couldn't understand what the operator was saying, but same situation. Got a message saying the IRA is filing a case against me. Told him I didn't believe he worked with the IRS and hung up. Hopefully it's not legit.
Got a call saying they were with the IRS on my vm. Called back and got someone who was not that great at speaking English. Automatically new it was a scam and hung up.
