Two games now i've had the same Duo que ruin it for me

If there was a solo only queue. then premade groups of 4 wouldn't be able to find matches. Then again getting stuck with a group of 4 premades is truly annoying since for some damn reason they always expect the random to go support. If you want a support ask a friend to support you, not a complete stranger.

It's rough when a duo queue set out to troll. Had a game the other day we had the front 6 turrets down but bot lane duo queue called for surrender and when it obviously failed they quit the game. We were doing well enough to have a chance if just one had quit. But of course even in solo queue you can still get two solo queue trolls. If Riot could start deleting troll accounts and make them start back at level 1 then at least there would be less trolls in the lvl 30 games. My brother got me playing this game and he is about done now from all the trolling.
