They claim to be federal grants

They said they did federal grants. The person I talked to said his name his name was victor Marshal. He told me I won 7,000 and it was a
once in a chance lifetime offer for being a good citizen. They said the federal government was providing the money

And how much did you have to [ay to receive this "free" grant?  Because there are no "free" grants, to get one you have to have a valid reason, and being a "good citizen" is not one of them.

They called me said I was to receive a grant of 7 grand, It was the second time they called and when I asked if they had called before they said no. Problem with that answer is it was the same exact guy who called me the first time calling me again and he went on to tell me that this was the first day they were allowed to make these phone calls. B.S. ! I hung up on him.

So did I! Its a scam right
