7 days ban because of my pc crashing

I’ve already got banned for 10m because of my bad internet connection, but since I got a better one, I’ve wanted to play ranked, I start a game and after 3 round my pc crashed (got a slow pc) I ‘ve managed to get back but it was already 11-3, after the game I go. 7 days queue ban, I made an ticket to riot and I was wandering if they could cancel it or not

Thanks for your responses
