Help! My Brawl Stars Account Got Hacked!

Hello there, it seems like my Brawl Stars account has been hacked. I've been attempting to retrieve it for approximately a year but without success. I have repeatedly sought assistance through the in-game support section, yet my problem persists without a resolution in sight. I reached out to Supercell through email, but they redirected me back to the in-game support section. I've attempted to reach out to the individual who assumed control of my account by adding my account from a different account, yet they adamantly refuse to relinquish it. I kindly request the return of my account. Identification number: #8YYGU9U9C
