Duo doesnt get their role and trolls but doesnt feed

So me and my friends were just in a game where we got mid and jg , what we wanted, their was another duo in our group and they didnt get what they wanted. They tried to get a bot lane duo, but ez didnt respond and presumably didnt want to go top what the adc pref in the duo got and so they then proceded to play vayne top and anivia support what my friend was hovering, and he hovered first. This wouldnt have been very bad at all honestly and i thought things would go fine after champ select, i was wrong. The anivia proceeded to go top and leave the ezreal to solo bot. I have the whole game recorded on plays.tv if thatll do anything in the sense that i can get screen caps. i reported them but i dont think riots gonna care because of the fact that they didnt feed even though leaving ez alone bot and going duo against a solo top definetly contributed to us loosing the game. I also dont think riot will care because of the fact that it wasnt ranked and it seems like they dont really care about the dedicated solo queue players.
