What should I do If I win a game that cannot be activated in my region, or if I receive a gift or key that does not match the game I won?
You should contact the giveaway creator to return the gift, and to inform them of the situation. If the giveaway creator is able to provide you with a replacement gift or key for the same game 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.

While according to your statement this is not a region issue, you still cannot activate your win and therefore inform the creator of the giveaway in order to give them a chance to fix things. Please write a comment on the giveaway and inform the creator of the giveaway about the situation as the rules and proceedings of the site are suggesting. If you don't do that you just make it look as if your took the key and ran with it.

Please take the time to familiarize yourself with the rules of Steamgifts as outlined in the FAQ and Guidelines.

Hello piyabhum.

about 2 weeks ago you were told to inform the giveaway creator about the issue. Yet there is still no comment of yours on the giveaway. You also have not only ignored our request but also the giveaway creator's attempts to contact you. This is not the behavior we are expecting from users of the site.

Please inform the creator of the giveaway about the issues you've had with the win.

The key is not used, is from humble bundle choice from June, 2023. I didn't know I had it, and it expires in 4 days, but I haven't redeemed it since I already have the game
