A Hacker Changed My Gmail Info and Google Support Still Cannot Restore My Account

I am writing this complaint because my Gmail account has been hacked and I have completely lost access to it. The hacker changed the email information, and I can no longer sign in to my account. When I realized I could not access my Gmail, I tried to use the “Forgot password” option and followed the account recovery steps, but I was not able to regain access. After that, I contacted Google/Gmail support and filled out the relevant forms, but despite these attempts I still do not have access to my account. I request that my situation be urgently reviewed, that my account be recovered if possible, and that my data and account security be ensured. I also ask to be informed clearly about the actions taken regarding this hacked account.
