Won a game but received a key for diffirent game.

While it sounds like a great deal, I'm not sure it belongs in the deals category. Daerphen gave you the correct answer though.

I assume the Ga creator massed up the keys somehow , or genuinely tough he is making a GA for that game instead.

Contact him in the Giveaway and explain the situation ... he can either provide you key for the game you won , or you can agree and you should if he want to to delete the giveaway cause he messed up.

last but not least , i do recall there being an option to change the game being given away . Im not entirely sure if that works for ended giveaways tho , but i would go for that option if possible.

Both just explain to support what happened

I have asked him to either delete giveaway or ask support to change GA name.
