please stop this

hi, guys there is an annoying thing about this game which is MY OWN TEAMMATES ban my champion most of the time, they say he is a hard champion, while i have more than 200k mastery points with that champ and they still ban him, EVEN THO I DECLARE MY CHAMP and even type that i wanna play it they ban him, can you stop this issue please riot ? like disabling the ability to ban a champion when another teammate is declaring it ? or punishing the ones who do it ? please do something about it, its very annoying
