Hacked Android Google Account Deletion Triggers Data Loss Concerns

I am writing regarding my Gmail account with the address "tmd4284**@gmail.com," which appears to have been hacked and then deleted together with all my emails. I use an Android phone, and about two days ago I realized that I could no longer access my account and that my Gmail data was gone. When I try to sign in, I receive the "Couldn't sign you in" error on the Google login screen. I contacted Google support and followed the recommended recovery steps, but I was informed that Google does not provide another way to sign in to this account and I could not regain access. I am very concerned about the loss of this account, as both the account itself and the emails in it are important for me. I kindly request that my situation be investigated in detail, that access to my Gmail account be restored if technically possible, and that I be informed clearly about what can be done regarding the recovery of my account and data.
