After waiting days to get help from live chat this it what they said

Hi there, I’m really sorry to hear that you're locked out of your account. To clarify, in order to make any changes to an EA account, including unlinking it from a PlayStation account, you must pass EA’s account verification process. This is a strict requirement designed to protect user data and prevent unauthorized access. Unfortunately, if the account can’t be verified, EA Support won’t be able to proceed with changes. I know this is not the answer you were looking for, but these policies are in place to ensure account security across all platforms.
