Good luck with your lawyer I guess..
This forum is not a hand holding forum (2FA)
It is not a lawyers or governments hand holding forum either..
If you can’t explicitly prove that account was yours, you probably aren’t getting it or anything out of it..

Owning the email address the account was created on explicitly proves that I am the owner of the account that was created with it.
