I guess they are still working this scam. I just got the same vmail. Said his name was "Officer McNellis" (?) in heavy asian accent of some sort. Sounded like a scam so I googled the number and can see many others have gotten it. The IRS doesn't work this way. I didn't return the call. Why don't these scams get shut down? I'm in an area with a lot of retirees who I guess are more likely to believe this is for real.
Sad to see that these people haven't been caught yet, but I guess it's not surprising. A few days ago I got a message from this number from a man calling himself Officer Ricardo (yeah okay) with the same thick middle eastern accent and was asking for my father by name. When I called back I got a woman who basically said my dad was guilty of tax evasion and that they had records of his taxes going back ten years. As soon as I called BS on this she said that a sheriff was going to be coming to arrest him, and when I questioned what kind of person from the government would warn a suspected criminal that someone's coming for them that's when she completely broke character and started cursing at me. I laughed and hung up. I found it weird that they didn't even ask for money, but they didn't like me questioning them very much.
This idiot called and said we owed $1,675 and that someone was going to arrest my husband for not paying his taxes and "hiding" money that we haven't reported!! Thought I would put the phone number in the computer to see what came up, and sure enough scam!! I knew it was because the IRS always sends out letters. I told the man, that didn't speak very good English, to send me out a letter....he said "no" we don't do that...yeah right! I called him back and gave him a piece of my mind and instead of me hanging up on him, he hung up on me! I called him back again and told him "he" is now under investigation!
