Need Google Account Recovery Expert (No Recovery Phone / No Old Device)

I need help recovering my Google/Gmail account.
I no longer have access to my old device or old location, and I did not add a recovery phone number. The account contains important data, and Google is not verifying my ownership (“Not enough info to verify” message).

I need an expert who understands Google account recovery methods such as:

Old session/cookie recovery

Device history verification

IP/location verification

Advanced account recovery options

Google support escalation (if possible)

I will provide all available details related to the account.
Looking for someone who has successfully recovered similar accounts before.

Please apply only if you have real experience in Google account recovery.
