Gmail Account Hacked and Scheduled for Deletion by Unauthorized User

I am the owner of a Gmail account that appears to have been hacked. On 25 June, someone gained unauthorized access to my Gmail and removed all of my access to the account. The hacker changed my password and recovery options and has also put my Gmail account into deletion, so I am at serious risk of losing the account completely. I have tried many times to recover the account using the available recovery options, but I am unable to regain access because all my recovery details have been changed and I no longer receive any codes or links. Despite these attempts, I still cannot log in or stop the deletion process. I kindly request that my Gmail account be urgently recovered and restored to me as the rightful owner, that the deletion process be cancelled, and that any unauthorized access be completely removed. I also ask that the security of my account be strengthened so that such an incident does not happen again.
