[CLIENT] Hextech key fragments problem

So I have big match history of wins on poros,rankeds and normals and didnt get a single key fragment. It's been already 4 days since last key fragment and in these 4 days i played 30-40 matches you can check by yourself and didnt get nothing. Also my friend from my country didnt get keys these days idk if its a bug or im just being unlucky ;(
