I Face Account Theft Issue with Supercell Game and Cannot Get Support to Recover It

The account shown in the attached photo belongs to me, and I played it actively until spring 2024. I had invested a lot of time and effort into it, unlocking costumes and making significant progress. However, after taking a break from the game due to sports activities, I changed my phone. During that time, my phone was stolen, and all my accounts, including my main Supercell game account, were taken over by someone else.

The person who stole my account even changed the registered email address. I have tried many times to recover it, but the Supercell support team has provided no real help, which is extremely frustrating. I am currently playing from a different account, but it is not enjoyable because my main account has all my best progress, skins, and hard-earned achievements.

I am asking Supercell to verify my ownership, restore access to my stolen account, and return all linked progress and items. If this is not resolved, I will keep filing complaints until the matter is addressed.
