Unfortunately, you are the target of a contest fraud. This is just a means of phishing for your personal information and trying to get as much money from you as the scammers who contacted you can steal.
How do I know that? How can you know that? The biggest reason, is that they asked you for an up-front fee. It doesn’t matter what they say that money is for and if that reason makes sense to you. If you have to pay any money out of pocket at all to collect money that is supposedly already yours, that is ALWAYS a scam. If a contest is sitting with YOUR money they don't need any more from you. Legitimate contests would deduct their expenses from the money that they already possess and then hand over the rest of it to you, free and clear with no strings attached.
Another reason I know this is a scam is that if you’d won a real contest, you wouldn't need to ask a question here. You'd have a lottery ticket with winning numbers on it if you entered a lottery, and you'd have your half of the sweepstakes entry with your numbers on it, if you'd ever entered a sweepstakes. Scammers always want their victims to believe that you can win a contest you have never entered, but they are lying. You must always actually enter a contest to be able to win, and your ticket or your half of your original entry form is required verification when you go to claim your prize. There is no other acceptable confirmation of winnings.
Any time you get an unsolicited out of the blue message with news that is much too good to be true, it is a scam, each and every time.

Cease all contact with these scammers, send no money. There is no award. You have not won a contest. You are dealing with thieves. Report the fraud to the police, to the FBI at IC3.gov, and to the Federal Trade Commission at FTC.gov.
