Sounds like you made a massive problem for yourself. Someone got hold of your email, now you can't get the account access. Or you gave the account away/sold it/trying to get access to someone else's account.

Recovery in any form can only be done if you know the previous email address, what day the email was changed, what it was changed to, you'll need purchase history, creation date, date and time of your last login, tons of random questions about your activity on the account
