[2021] My friend's account got banned for no reason

hey all

I have a friend whose account was banned in the game when we were playing a Ranked game, he got a notification that he was banned from the game because of cheating, my friend did not use cheat or hack programs and he also has a video clip during the Ranked game when the ban notice appeared, and also strangely when he logged into his account The second was blocked right after entering the game, my friend how much money he paid inside the game to buy characters and costumes, he contacted direct technical support, but they did not provide him with any service, so I put this post here We hope that you can help us solve this problem
