deleting or unlinking a disabled account

My PS5 is linked to a disabled account. I created a new account and tried to link it to my PS5, but I am unable to do so. I have no idea what the email was or what the login information is for the disabled account. How do I delete it or unlink it from my PS5? I have spent at least an hour now fumbling through the EA help menu. I hit contact us and tried to create a ticket, but it won't submit either. This customer service is not very user-friendly and is quite aggravating. Please, can a person reach out to me to help me? I am not able to play and save any data on EA games, and I am getting to the point where I am considering canceling my Battlefield 6 preorder and just giving up on playing any other EA game ever again.
