WePlay Account Banned After Unauthorized Use by Family Member

I have been playing the WePlay game on my Android phone for a long time. One day my older brother entered the game without my permission and used offensive language in the game. The next time I tried to log in, I saw that a match had been started and then the game never opened again, so I understood that my account was banned or blocked. This situation has been going on for about 1–2 years and I have not been able to access my account or play the game during this time. I would like my WePlay account, which I lost access to because of this incident that did not happen with my consent, to be reopened and my access to the game to be restored.
