14 Day suspension for having a bad game, please help.

In the match I was playing Diana top against Akali. I brought the wrong Masteries, running Fervor on Diana is not Ideal, and I think the wrong runes but I'm not sure. I lost to Akali, HARD. at around 10-15 minutes she was just diving me under tower and slaughtering me. There was absolutely nothing I could do. It was a bad game and i did have 9 deaths at 10 minutes. So of course the team assumes I'm feeding. I got reported and the system said that I was kicked ONLY for this one game according to the Pop up that told me I was suspended. How is this in any way fair? One bad game and I'm banned for two weeks, it's even worse since it's URF week please get this fixed as soon as possible.

PS. I read that there is absolutely no way they will change the auto suspension system, please tell me that's not true. Otherwise I might as well quit the match and take the leaver. 5 sessions of 20 minute waiting, 100 minutes. 1 hour and 40 Minutes vs 2 weeks. This is outrageous. Please.
