When ADC rage cos being ganked constantly then left to top

At the beginning of the game, my ADC kept complaining me and said i had no CC as a Mord supp when it is clearly just a normal game. After constant ganks from enemy mid and jungle, she rage and left bot lane open so she can go top. Entire chat was her raging in early game and even try to promote argument in the team. In the end we won, but i had no choice but to report her for being toxic and negative.
