I heard the phone ringing just as I was leaving the house but chose to just let the answering machine get it. When I returned home I played the message and it said the same thing to me as everyone else. That this was the IRS and not to ignore this message or they would take action against me. The first thing I did was google this number and I saw all these posts. Thanks everyone, glad I came here first before even wasting my time calling these people back. What a scam!
