Old account has primary e-mail and I'm locked out of the old account that had it
I used to have an iPhone 4 back yesteryear and I made it's apple account use my primary e-mail since I made it around that time. Since then I've long forgotten my security questions, and since I don't have them written down anywhere, and I may have either mistyped or said something wrong for them when making the questions, what can I do? I've tried everything, and this is my second time attempting (Over the course of a couple years) to change my current account's e-mail to that primary one instead of a secondary one I had to use to make this account, yet that original account still stood using it. Whenever I try to reset my security questions, it says "Not enough information to reset security questions" (May not be an exact quote) which then bars me from the rest of the process of figuring out how to move things over to the other account or changing my current one to have that e-mail. I'm afraid of trying to log out/in on my main iPhone due to the nature of how finicky this has been
Any resource I've tried either has information that isn't helpful in this case, or due to the uniquely problematic nature of my situation, which leaves me little choice in doing the one thing I didn't want to do about it; ask a public venue that would be most likely to know
