These guys left a message to call 609-299-1691 because you are in trouble with the IRS.  It is a scam.

Enforcement action executed by the US Treasury against me (bah,bah bah). Back room noise sounded like a boiler room operation. Gave name as Dennis Quaid (like the actor) with an Indian accent.

US treasury Dennis Quaid. Indian accent. Got another call Indian accent from a Washington area code that time he was from IRS. Prank called him back and he was very profane in talking about Americans and the U.S.... Beware of Indian accents trying to collect money over the phone.

I too received a call from Dennis Craig today from number (609) 299-1691, or that is the call back number he left on my voicemail.  Oddly enough,  two days earlier I received a call from Kevin Mason from (202) 753-0633, he also left a message on my voicemail.  Same man, same voice, accent and same message word for word with only the name and phone number changed.  How lame can they be?  I realize it's a robocall, but you would think that if they were that desperate for cash they would lay heavy on the due diligence to avoid such screw ups.  I am so tempted to call the Kevin number and ask for Dennis and vice versa, but worried I may get someone on bad day.  Just saying...

Left on my home voice mail and I had a missed call from the same number on my cell. Indian accent - I thought he said Dennis Gray urging me to let him( US Treasury) help me. Haha
