How do i recover my account when i dont have acces to my email

I want to change my EA email address, but I don't have access to the old one anymore, so I can't enter the verification code to change it. I can log in to EA using my PlayStation account, but I need the email address for certain things like the FC Companion app. I've been trying to speak to someone for ages but it seems very difficult. How can I get on the phone with someone at EA?
