Banned for being New

So, I am a new player to League of Legends. As such, I played a game where I got killed A LOT(17 times to be exact) and we lost the match. I was reported as "intentionally feeding" the other side. This lead to players reporting me and I now have a 14 day suspension. I am still learning the ropes of the game. In the Summoner's Code #8 says "Leave No Newbie Behind!" and I feel that the people who reported me are in violation of this. To be fair, they didn't know I was new. I have requested a removal of the suspension so I can practice playing against bots for a while. Is there anything else I can do?
