I received a call from this number & was glad I answered. It was the IRS & this is not a scam. If you've been a victim of identity theft or someone filed a tax return in your name...it would be in your best interest to answer if they call back. I called the number back that came up on my caller ID & got a recording that said the number was not working but I spoke with the IRS agent & actually met with him. This is not a scam...this is for real. My identity was stolen & someone filed a tax return using my info in 2011. The IRS is investigating it & that's why they called.
