So I'm level 7 and I reached level a 3 like a day or 2 ago but still i haven't received my free reward of 400 rp, i don't know if it is a bug or something, how can I solve it, or maybe I need to wait to lvl 30 for getting it >:( Thank you for answering.
They don't do it anymore. Instead, they give you a free premium hextech chest.
its not even a premium chest they give you a chest with garen and ashe and a garen skin
Had the same problem. There isn't anymore free 400 RP http://boards.na.leagueoflegends.com/en/c/miscellaneous/ZGErnvY4-hextech-crafting-new-player-chests-to-replace-400-rp
