Hi Erika, Microsoft regularly run out of popular rewards like the Riot Games codes in some regions, this forum is just a user to user forum, no-one here knows when Riot Games codes will be back in stock in your region, you just need to check the rewards web page regularly until the Riot Games codes are available again.
