IRS scammer.

Said his name was David Gray.  I understand he was an IRS scammer.

Just got this scam call. It's a bit disturbing because it is so close to where I live. Apparently the job market is so bad scammers have been putting in overtime lately.

"David Gray" has called twice so far this week.  Really, if you want somebody to believe you, don't sound like you are a British speaking Indian, and don't sound like a recording.
Remember, the IRS will only contact you by mail for things of this nature.
He said the reason for his call was in response to an "enforcement" action by the United States Treasury and "help us help you."
