I got ban for no reason

Hey riot i was in champion select and when it was 0 second it doesent go to be 100% but it was like a problem. and i closed the game and when i tried to join again it said logging on but just saying logging on and it doesent open the reconect button and 5 min later it joined to game and i reconected and then i remaked but i got ban for 5 games 20 min. Pls remove my ban because i didnt stayed afk 5 min for no reason but i had one reason i could'nt log in to lol and to do reconect. Pls remove my ban cause this game is very good.
