Duo purposely losing the game for ranked players

I’m bronze 3 in ranked and I just had a match where my team was winning and we just so happened to have a duo who weren both jg one was a trundle another was an anivia and throughout the game they were purposely using walls to trap our teammates into turrets and enemies to the point where it was impossible to team fight eventually the enemy team won and all I have to say is that’s really some bs I reported them but I’m not sure if anything will happen and I’m pretty sure I’m not the first victim they did this to nor will it be the last if they don’t receive some type of ban or warning
