Hacked Gmail Account Recovery: How to Delete an Inaccessible Account

I am writing regarding my Gmail account, which has been hacked and accessed without my permission. I use Gmail on my phone and I recently realized that I have been completely locked out of my account. I can no longer log in and I believe an unauthorized person has taken control of the account. This situation makes me feel unsafe, as I do not know how my personal information and any linked services may be used. I request that my hacked Gmail account be permanently deleted as soon as possible so that no one, including the attacker, can continue using it. I kindly ask you to review this situation urgently and confirm the deletion of my account.
