I Face Account Theft Issue With Clash Royale and Cannot Recover My Supercell ID

My Clash Royale account was stolen and I have been unable to recover it despite multiple attempts. It was originally linked to my Supercell ID using the email address y**************@gmail.com, but after the theft, the email was changed without my consent. All of my in-game friends were deleted, and I no longer have access to my player tag or any account details. Because of this, I cannot use the in-game support system to request recovery.

I know exactly which devices and locations my account was accessed from in the past, and I can provide this information for verification. My account has been stolen for a while, but I initially did not pursue recovery because I was focused on preparing for the YKS exam. I attempted to retrieve it once, but after failing, I decided to postpone further action to avoid distraction.

I am requesting Supercell to verify my ownership, restore my account to my original email, and secure it from further unauthorized access. I expect urgent action to protect my years of progress and hard work.
