Apple makes it easy to request legal access to things you can’t get when you can’t reset the password via normal channels.

If you’re not a lawyer or part of the government, you probably won’t get much help there. Same trying to get Apple support to disclose information or rescue an account if you can’t just follow the instructions for forgotten passwords / lock out.

Apple surely has their people trained and they know full well what you want and they are saying no. If you’ve been through 3 people, you’re not going to get a better audience by stalking / brow beating someone in my experience. Apple said no to the US FBI for unlocking phones and accounts, so they’re likely not going to cave with someone that’s not able to unlock purchases on their account.
