How do I unlink this from my PlayStation account?

Hi there. We have an article for unlinking accounts here that should help. Unfortunately, content and progress do not carry over when moving a platform account to a new EA account. Just something to keep in mind.

Thank you for the reply

I don't know if I'm dumb enough not able to find that the article has any solution to unlink an account which doesn't belong to me and I don't even know this email address(pa*****@lettersboxmail.com) nor password so there is no way for me to log in and unlink it from my PSN account.

I still havent been contacted by an advisor. Can you please help me? I just want to play battlefield

Please wait for an advisor to respond. Unfortunately, we can't help with account related issues over the EA Forums.

The EA forums are literally the only place to actually talk to a human being. Additionally, every case I open, I get an "advisor" automated email back to just read an EA help article. 

When you fill out the form, make sure you select "Update EA account" in the "What kind of issue are you having?" field.

that hasn't gotten me any closer to actually speaking with an advisor.  once again, filling out the form only results in an automated email response referring me back to the EA support articles, and because the email is not monitored, I have to repeat the vicious cycle of going onto the articles to fill out the form to once again receive an email to READ THE ARTICLES AGAIN

Are you logged into an account or trying to submit a case as a guest? If you're using the guest option, try logging in to your account. 

I am logged into a new gmail account because my original EA account is linked with an old dead email, so unlinking through that old email is literally impossible because I cannot log in to unlink it. And I cant link the new EA account with my xbox because only one account can be linked at a time. Every support ticket I have sent in has been using my new gmail EA account, none of them have been as a guest.
