Just got this call and did not answer. I tried calling back because my mom is visiting LA and the call never when through so looked up the number to be sure. Thanks 800 notes! I then googled this and the IRS has issued a warning for phone calls exactly like this - http://www.irs.gov/uac/Newsroom/Phone-Scams-C ... 5-Filing-Season

This number called me but hung up before I could pick it up. Let them try and pull that BS with me. I also already warned all my friends and family about these losers.
These guys are back at it apparently; check out how many of these reports are new for June 2015. Called my cell phone just now and only let it ring for a couple of seconds. It's call-baiting; they want you to call back out of curiosity. Don't bother.
