I can’t log into my account so I literally cannot play the game?

Been playing Battlefield 6 since launch. Tried to play  today and it’s asking me to go to an email that isn’t mine to sign into? So it’s asking me to get the code from an email but this email has nothing to do with me or my PlayStation account? Literally cannot get in contact with Ea pulling my hair out how am I ever going to be able to get online? I’ve had to make this new account on here to post to try and get some help? The help chat just says to me this isn’t something we offer support on and I can’t get through to an agent.
