Champion select

So,i just got placed midlane in a ranked game and my support with nickname "supportGirl" picked akali (which i was going to play on mid) and i thought that we're gonna trade champions like normally..and then she started typing in her native languege and she rejected my trade...i picked morgana,and i am the worst morgana player that the world has seen,so i had to dodge the queue and i got to wait for 5 minutes before queuing again..and i lost 30+ LP which is NOT A SMALL AMOUNT,so why dont we just lose 1 lp per dodge or why cant we kick the trash out of the champion select? and when we try to report players whom act like that they dont get banned...
