The worst game I'd never seem, and I need someone who can help me to carry forward the truth

In a normal blind pick , I choose the yasuo to go mid, my teammate Teemo was top, Thresh and Ashe were bot, and kaizi was jg. At the early of the game, my beat their Zed for twice under many ganks from their jg, Elise. Midline was the only line which in a good shape, teemo was 0-4 beaten by their mor, at that time, mor got fed a lot, and no one can kill him alone. Therefore, teemo just went mid and stole my minions without my agreement, and said nothing( no explanation, no apologize, seems like he did a negative attitude because he was 0-4, and never ask for help), also fed their zed from 0-2 to 1-2, I didn't even say any offensive language to him. Then I went top trying to fight against their mor but I failed, my teammates began to laugh at me and using crude language. I thought I should go back to mid which is my line to enlarge advantages for out team, cause I already killed their zed 2 times. In that case, I was still 2-1, I was the only player had positive kda. The I persuade teemo go back top which is his line, teemo said shut up to me and kept farming at mid. From this on, my teammates started laughing at me called me trash and newbie. I was pretty angry and wanted to argue with them, but I endured and mute them. Cause silence probably was the best way to stop this argument. After a few mins, I canceled the muting, I found out they distorted the facts and tried to let the other team believe their lies, in order to help them reporting me. I was the only foreigner in this game and probably they all knew that because it can be reflect by my typing( my English isn't pretty good, so there might some mistakes in my typing). I need an explanation and a method of handling from official. That's a really cruel game that I'd never seem, I feel really bad and strong racial discrimination. Everyone tries to laugh at me, I can't stand it. 大家好，我是一个玩美服的中国玩家，在一局blind pick中，我选择yasuo走mid，我的队友Teemo走top，Thresh和Ashe是bot，螳螂是jg。在游戏初期，我在他们队打野Elise的gank下，击败Zed两次。目前mid是唯一状态良好的线，teemo被铁男击败到0-4，那时铁男被喂的很肥，没人能杀死他。因此，teemo只是在没有我同意的情况下走到了mid，偷走了我的兵和经验，当时他什么也没跟我说（没有解释，因为他是0-4，所以他似乎持消极态度，从不寻求帮助），还把Zed喂从0-2至1-2，我什至没有对他说任何冒犯性的语言。然后我去尝试对抗他们的铁男，但失败了，那时我的队友开始嘲笑我，并使用粗俗的语言。我认为我应该回到中间，这样我扩大优势的路线，因为我已经杀死了他们的zed 2次。在那种情况下，我仍然是2-1，我是唯一拥有正kda的英雄。我尝试说服teemo回到他的路线，也就是top，teemo说对我闭嘴，并在中间一直喂。从这时起，我的队友开始嘲笑我，称我为垃圾和菜鸟。我很生气，想和他们争论，但我忍受了他们并使之静音。因为我认为沉默可能是阻止这种争论的最好方法。几分钟后，我取消了静音，我发现他们歪曲了事实，并试图让另一个团队相信他们的谎言，以帮助他们举报我，并一起嘲讽我。我是这场比赛中唯一的外国人，也许所有人都知道，因为它可以通过我的打字反映出来（我的英语不太好，所以打字时可能会出现一些错误）。我需要一个解释和一种处理方法。这是一个非常残酷的游戏，我从未玩过这样的游戏，我感到很不爽，很难受，我感到自己收到严重的种族歧视。所有人都在嘲讽我，我实在受不了了！！！！
