League needs to Investigate the issue when anyone is being reported

Its funny when i go into a game, and when we do well, someone always wants to report someone because they did not do well and they just rage so they report for no reason. I have never complained about people and their terrible gameplay, nor their lack of skill, nor have i ever been out of line when talking to the enemy team. But when i get messages when i login saying we all have bad days and what not, and that i need to take it easy on the verbal abuse, like seriously? lol, for me to get chat banned for 21 days, yea it may not seem like a big deal, but its the fact that they ban me, and not investigate the situation. Its as if they really dont care. I have recorded almost all of my games and those videos can show you that i do not use abusive language and what not. So please if you could investigate the situation, thatd be great. Because ive put way too much money into my account, and im not going to do anything that would jeopardize or have my account banned permanently.
