Supercell ID Email Change Issue Unresolved

I’m incredibly frustrated with Supercell’s customer support. After changing my Supercell ID email, I never received the verification code, and instead, I’m constantly being told there’s "suspicious activity" on my account, resulting in my request being rejected. When I tried to contact support, the conversation was immediately ended without any solution. I even created a dedicated email for account recovery, but still no positive response or help. This is unacceptable. I’ve invested so much time and effort into this game, and to be completely ignored by Supercell’s support team is extremely disappointing. I need this issue resolved as soon as possible. Supercell, please fix this problem and provide me with the support I desperately need.
