Banned for no reason?

So I was playing Halo 5 arena 2v2, and my teammate wasn’t doing too well so he just left the game. And obviously that didn’t make me very happy, in fact it made my score plummet. And a couple deaths later- BOOM! I was banned because my teammate left the game. Why did I get banned for another player’s misconduct? Another time, I was playing 4v4 and all the sudden a screen popped up, I had lost the connection. So I thought to myself, “Its okay I can just join another match,” but I couldn’t, because I was banned! I’ve never actually killed another player, but I have been killed numerous times by other players, and before you ask, yes I did report them, but instead of them getting in trouble, I did, and guess what? You’re right, I was banned. I’ve been ran over by speeding warthogs, shot by tanks and banshees, but yet I am the one getting banned. I haven’t even had the game for more than a week. But I’ve been banned numerous times for other player’s mistakes. 343 needs to fix their banning system, like now. This is unacceptable, 343 you need to get rid of the ability to harm teammates, and don’t tell me its hard, or it affects the game, because it needs to happen. And if this message doesn’t reach 343, well then I guess we’re all dead. THIS GAME IS BROKEN, PLEASE FIX IT!

I have also lost connection many times, and it’s not my internet. The servers are just not that great. I have joined many matches, but they were already in round 3 when I join. What’s up with that?

There is a ban thread at the top of the page please post your question there.

Already did! Thx
