The scammers will claim you need to pay some form of fees in order to receive your prize. But, once the fees are paid, the scammers will disappear and you will not receive the prize or money you were promised.
Remember, never send money in order to receive a lottery prize because this is how lottery scammers trick people into sending them money, or this is how they make their money. And, legitimate lottery companies will never ask their winners to send money in order to claim a prize.
