Hello charlesmarco69.

You should contact the giveaway creator to inform them of the situation. If the giveaway creator is able to provide you with a key that can be activated in your region, then you should mark the gift as "Received". In all other cases, the gift should be marked as "Not Received".
When marking a gift as "Not Received" it's recommended that you leave an explanation in the giveaway comments as a reference for both the giveaway creator and our support team. If the giveaway creator is not able to provide a replacement gift or key, they may ask your permission to delete the giveaway.

Please be more mindful if a situation like this occurs again.

Thanks.
