2 premade of trollers in d3+

Cant believe what happend to me, i had promos for d2, and in the first game of promos, everything was fine, i had an anivia supp and tahm top, they were both premade cuz of their club name, and after 10 mins, its was a pretty close game, they decided to troll,anivia was W people that were recalling, and tahm was eating people and running into the enemy team, i was pretty ubset, because they had no reason to troll, no one was flaming, everything was ok, we had high chances of winning that game, they just suddenly troll, especially in my promo game :( Feelsbadman (ik i am bad at english i just wanted to tell my story) And ik they wont get banned, because enemy team likes taking the free win so they wont report them, and i rarely see someone getting banned cuz of trolling,i really think riot should punish more people that trolls.

EDIT:just finished my promos, i lost the last game because our adc rage quited after we died on bot, the score was 3-2, really easy win.
