Riot please help, extremely toxic teammates

I was just in a game where I started off telling my team im in my promotions so im going to try hard, we were all having fun and I got really ahead so I jokingly said, I don't know if I want to end yet im having too much fun 1v5. My Mf Ezreal and zed all were in a trio que and decided to afk and said have fun, they all sat in the fountain and ran around our side of the jg killing the mobs, when I was jg. They were also just instigating the whole time saying oh thats too bad this is your promos isn't it. As well as purposley running down top and bot feeding. Then after the game I said I was going to send in the game footage to riot, and they harrased me. Disgusting teamates don't make me want to play. In promos and my team afks and antagonizes me through it. Please ban them or suspended that because that's absolute bullshit.
