Please help me

I have tried reporting toxic players after games but it hasnt worked yet. Today I was in a game who flamed me after when i dodnt smite red, she left me with the reset full health golem at lvl 1, so i took 5 or so farm so i could get lvl 2. She then spent her time taking my jg and lost her turrets at around 10 minutes and then fed the rest of the game after telling us she would do so. (i can post what exactly she said if asked) and she ended the game 1/11/1. I would love to hear responses back maybe from rioters because i am 100% sure that this banning for toxic behavior thing doesnt work anymore. I look forward for replies. Thank you.
