My account was banned by mistake

A few hours after I went offline on the 14th, I received a ban email. I checked the data to make sure there was no cheating. I only play this game on my personal computer. I filed a complaint requesting to unban the account, but it was rejected. On that day, I only played the control mode, and there were a few rounds of players that did not load into it. In a round, I only have one teammate and four enemies. Play 30 kills and 6000 damage. I know that on April 6th, April 14th, and March 21st, some players were banned by mistake because the redspider team tested the hackers who attacked the server. I think I was identified as a hacker attacking the server because I got a high score in a game where players were missing. I'm very sad, I'm a victim, I just want to finish the game, although I only have one teammate, the opponent has four, I appealed more than a dozen times but was rejected, I really have nowhere to go, I spent two thousand hours and Thousands of dollars in games make me sad.
