U.S. government grants WU fraud, credit card fraud, checking account fraud 233 area code unknown

I received 2 calls in the last 2 days from U.S. government grants. they pitch a $7000 grant that I qualify for and I'm supposed to ask "How did I qualify?"

they say I got it thru paying my taxes on time and not having bad crdit/defaults on loans. Then they ask "how do you want the money? there are 3 methods: checking acct deposit, debit/credit card deposit, and Western Union transfer. Anytime WU is mentioned, it means a scam, so I wanted more info. 

I asked for WU transfer so they said to send $250 for processing and then call the Sr. account mgr. at this phone no: (202) 738-1123 and tell him the money is available then he'll give me the account transfer numbr for my WU money.

I didn't do the WU transfer, but they did call me back from this number: (233) 423-3423. Again, they asked me the same things: checking acct. transfer, debit card transfer or WU transfer. Just for giggles, I said: "lets do debit card transfer." I told him a fake debit card no. and I transposed the last set of numbers. He knew it was a fake and hung up on me. 

do not believe in money for nothing. There are no grants unless you apply for them in person. This happens when you sign up to do online surveys and everyone is hungry for your $$$
