Lost a game and got demoted because teammates (including jg) were typing during Baron

It had been an uphill battle, enemy jungler camped me (as GP) babyguarding his tryhard Quinn. Jungler and midlane spammed pings all game, botlane constantly pushed up to enemy botlane turret. Ahri mid and enemy Diana mid took turns deleting and aceing eachother at the same time. Fastforwarding through the struggle, We made a lucky Ace around 27:00 right before the enemy adc and the Quinn hit their "maw of malmortius balanced powerspike" and all that was left alive was enemy jungler.

With victory nearly in our hands, our jungler decides to type during baron while we can all clearly see Lee Sin roaming around on top of the baron cliff, I try zoning with barrels while the rest of the team stands still autoattacking the baron (save for our Jhin who had an unlucky game)

tl;dr lost a freelo game because of team typing during baron

Is this elo hell or spilt milk?
