Who is the provider for your old email account?
Approximately when did you last access it?
Yes I am here
The only way to regain access of the account is to use Google's recovery methods.
Sometimes it can take several attempts to enter all the information they have requested correctly before they will unlock the account for you.
Have you truly exhausted all of their methods?
Even if you can give them enough details about how you used your account, people you emailed a lot, when it was created, folders or labels you created... you might have a shot.
BUT, if you have truly exhausted all of these recovery options then there is no other way around it. Google will not bend the rules or make exceptions.
Sorry to have been the bearer of bad news on this occasion.
I am a user of this site, just like you.
For refunds, you will need to contact customer services.
Have a good day.
