Complaint Review: United States government grant department

I received a phone call from "The United States Government Grant Department" offering me $1,000 Grant to use for anything I want.  I told the caller, who had a heavy India accent, the United States Government never calls citizens.  He ignored my statement asking for my mailing address, I gave him one that does not exist.  He asked me for my age, I asked him for the web site, he gave me a bogus web address.  Ripoff Report #982565 came up when I tried the web address through Google.  I told the caller I knew he was a scammer and hung up.  He called me back immediately and could not understand why I hung up.  I told him he was breaking the law, is a criminal, and needs to go to jail.  He screened "You are a criminal" and I hung up once again, he did not call me back.
