In five ten minute lower priority queues? I didn't do anything -- is there a way to dispute this?

So, I loaded into a game. It went to the loading screen, which never even loaded! It was just a black screen for about 2-3 minutes. I was really confused so I minimized the game and I had a "reconnect" button option, so I pressed it. It reloaded my connection, put me into the game, and right as I was doing so we were surrendering. The game couldn't have been going more than 2 minutes (accounting for everyone's loading screen and all) I am being accused of being afk but I never was. I was here staring at a black screen the ENTIRE time, and I don't know how I could have been reported so fast; the game had hardly begun and I never even loaded into it! Is there a way to dispute this? This isn't the first time this has happened to me and I really want to get more into league but the more this happens the more I'm turned off from playing.... any suggestions?
