You need to create a "Request New Winner" ticket if you cannot contact a winner to deliver their gift, we cannot help with that with a user report

The winner said that when he tried to claim the gift, he could not because you canceled it. Then he could not comment about it on the giveaway because he was blacklisted.
That was 2 days after the giveaway ended, if that's the case we won't be able to reroll the winner,. You have to give them a week to claim their gift.
