Urgent Gmail Account Recovery Assistance

My primary Gmail account has been hijacked and I now have zero access to it Hacker changed recovery mail and recovery phone number. Forgot password option not appearing as well codes are sent on other mail that i dont have access. I already exhausted Google’s standard recovery forms and every suggested self-service step, but each attempt ends with the same rejection message. The account was never linked to a phone number or secondary email, so I cannot rely on the usual verification codes.

What I need is expert, legitimate support to regain full control of the mailbox and lock out the intruder permanently. The successful approach must stay within Google’s policies and local laws while maximizing every technical and procedural avenue still open—escalation paths, forensic evidence gathering, or any advanced methods you have used successfully in similar situations.

Deliverables
• Restored, working login to the original Gmail account (inbox, Drive, and linked services intact)
• Detailed summary of every recovery step taken so I can repeat the process if the issue reoccurs
• Post-recovery hardening checklist (security keys, 2FA setup, backup options) tailored to my situation

I’m ready to move quickly and will be available for real-time verification calls or document uploads you might need during the recovery workflow.
