National Media Group Mail and phone scam ?, Nationwide

I received many phone calls from the National Media Group.  Finally, after many attempts to contact me, they sent me a claims document for a pending cash grant claim for $20,978 (DOE).

Of course, they asked me for my credit card information in order to send me the paperwork and information regarding the processing of my so-called government cash grant.  

First of all, if it's a government grant, why do they need my credit card information.  Secondly, if it's a government loan, why are there people from overseas for customer service processing American government grants.  

I feel embarassed and naive thinking for a second that there are these government cash grants.  With president Obama working actively to "spread the wealth", I hoped this was part of the 700 billion dollar economic stimulus package.  To be honest, I sure could use it.  

Are there really such programs that exist in our government today?  If so, who could I contact other than the "National Media Group" or characters like Matthew Lesko?  

If someone knows, could you steer me in the right direction?  Otherwise, just call me a knucklehead and just accept the obvious; it's a scam!!!
