I am always getting support, wtf?

When I'm playing ranked my primary is mid, secondary is top/jungle and i always get support and quit the game, then have to wait 30 minutes. The problem is not that I need to play support, it is that i can't play bot lane i have no sense of gank, i can't trade properly, can't wave freeze, don't have proper vision and it is fucking boring to play one role all the time, so i just close the game. I can't even play where i can play (that sentence is weird i know). If I am not support then i would be adc, that's really fricked up. Please fix that, because i know i am not the only one with that problem. I know that support is the least played role, but there are things that could make it more playable and fun (more gold -> more items -> more interest in supp role).
