I just got the exact same call.  Original call came from an unknown #.  When I answered it, everything was verbatim to what you were to except my grant was 9,000.  I was preselected from a demographic survey done in my area.  He said my name and phone number was chosen.  When I asked him what my name was... The scary thing is, he KNEW MY FIRST AND LAST NAME!!!!

He gave me a confirmation # and told me to  call 202-470-2647 right after we hung up.  

I DID NOT CALL the 202#!  This guy also had a very heavy Indian type accent and got snippy when I would ask him to repeat himself as I could NOT understand him!!!

Ok, this was not a number that called me but a number that was given to me to call , first off i got a call saying i got a grant for $7000 and from the US Commerce in Washington D.C (And being me already red flags are going up but i wanted to know how deep the rabbit hole goes and all i need to do was verifie some info, i did so and then was given two id numbers and a phone# 202-470-2647 to call this number to talk to Michele Williams and they would deposit my checks in my bank, so i called said number and gave the id number to her and she told me all i had to do to get this money deposited in my account was to wire her $190 processing fee red flags went up so i informed the gale that i was not interested in a scam and hung up 20 minutes later the first guy calls me back and ask if i got ahold of Michele and i tell him yes but after talking to her i realized that it was a scam and that i am not interested plus i look the number up and it came up on a list of numbers from India (forgot to tell you this guy had a very heavy -I can bearlie speak English accent) The go just freaks out starts screaming at me "you lie who told you this you lie f*** your mom f*** your mom who told you this" with which i replied wow your really just convinced me that i was wrong and made a mistake and the guy keep yell at me "F*** your  mom f*** your mom who told you that f*** your mom f*** your mom" the cursing just keep going tell i finally hung up i did stay on the phone for about 2 minutes after the cursing started making fun of the guy for doing such a good job at convincing me that he was not a scam artist from India, because nothing says i'm legit like telling someone F*** there mom and calling them a Lier damn i was so convinced at this point i don't know about you wish i would have wrote down the number that called me first but i hope this is helpful to someone!
