 This document says “without proof of your identity via security questions and other carefully selected criteria, Apple Support can't help you reset a password or perform any other actions on your account.”

Thus, we can do nothing to help you if you can't answer your security questions successfully, except to mention that Apple support might help you if you have an extenuating circumstance (e.g., you have the receipt for your purchase of a pertinent device with its serial number on it).

If you want to contact Apple support to discuss any possible extenuating circumstance, see these support options:
