Please add a function of reseting my account to 0

I play games to 5500, and i want to return back to 0 trophie and redo again.

There is.

Go to any clan (or make your own), then write /clean. Once you are prompted to restart the game, and you log in, there it is, your account has been reset.

thank you for reply.
I need to reset my trophies to 0, and back to arena 1.
/clean only reset level to 1 but trophies and arena not reset.
