Something has to be changed

I selected Support main (Which I do all the time) and mid back up. I, of course get support and top non banning position on the team. My own team tells me to go Top. I refuse saying I picked Support and Mid. They BAN MY SUPPORT CHAMPION out of spite. So I leave and get banned for 5 minutes..... Seriously Riot, if your queue is supposed to be set to be what you selected, there is no way this should happen. It's a dirty thing to do to someone who picked what they wanted correctly.
