Ranked issue champ select bug

Just tried loading into a ranked game and upon finishing queue between actually being put into the lobby my client black screened and i could still check my friends list and everything it said i was in champ select and i could here the timers running down I was first pick as i could here it selecting me to make bans but i could not see anything or do anything I was forced to close the client therefore causing me to lose Lp and now if i lose a game in the tier i was promoted into i will be instantly demoted Please fix your game riot If my client bugs on my brand new pc and im forced to leave a game because of an issue with your game why should i have to take the penalty not to mention having to wait to play another game because i had to dodge champ select??

This is just as awesome as going 7-3 in my placement matches and being placed in the hell your game has created also known as bronze
