My psn account is bound to an ea account that I don't know about

Hi, I want to play apex on my ps5, so I logged into my ea account and tried to bind to psn. My psn email address is [edit: email address removed]. My id is shaowinds

When I bound the psn, I was prompted that the PSN had been bound to other ea mailbox [edit: email address removed].

But I don't know this mailbox at all, I have basically never played any ea games on ps before, otherwise I should be bound to this mailbox that is now logged in.

I suspect that my psn account was leaked, which led to my account being used by someone.

I have no idea what this 7a.... email address is, so I can't log in. Now I can't bind my real ea account with my psn. I hope you can help me solve this problem, thank you!
