Unfairly banned after 1 (ONE SINGLE) game

I play taric supp. It gets clear my ADC don't know taric both by his play and he then confess in chat. So i roam mid and our mid start spam pinging and then goes afk. He then whines in chat and ask everyone to report me. Which they do, both my team and enemy team. Now i got instantly banned for 14 Days after only 1 game! Is there anyway to get some official to look at it?
