Hacker Steals Gmail Password and Drops 2,000 Trophies on My Brawl Stars Account

I want to report an account security and trophy loss issue I've experienced in Brawl Stars. The password to the Gmail account linked to the phone I use for the game was somehow discovered and stolen, and someone gained unauthorized access to my account. This person is now playing using both their own account and mine, and they're deliberately dropping my trophies on my account. I can still log into my account right now, but since this person also has access, my trophies have dropped significantly. I've lost around 2,000 trophies, and trophies I worked hard to earn over a long time were wiped out in a very short period. This has cost me a lot of effort and completely ruined my enjoyment of the game. The other person's in-game ID is hamzacapalar. My in-game name is jitteryaptalhamza, and that's the actual account where the trophies were dropped. I'm requesting that my account's security be secured, that this person's access to my account be fully blocked, and that the roughly 2,000 trophies unfairly lost be restored to my account, jitteryaptalhamza. I'd appreciate it if the necessary investigation could be carried out to resolve this situation.
