banned for no reason

On May 15, my account was banned for repeated violations that I have no idea about. I have always played fair and have not used any cheats or similar tools. After the daily update, I completed the Colosseum, celebrated my 4th place, and left the game. However, when I logged in again, my account was banned. There are no registered violations in my account's violation history, and the list is empty. The technical support team sent me to the user CG_LucifersDaddy on the forum, who has not been active for a long time. What should I do in this situation? The appeal form has already been filled out three times. Why is there no feedback from the players? What should I do? How can I unlock my account?
