Can't unlink or sign into EA account because email is deleted

I made my EA account 14 years ago when I was in high school the email this is connected to it is deactivated as well. (Yahoo). I've talked to 4 different agents and I gave them ip addresses last 4 digits of card number everything needed to verify that my account is mines and they still denied my request to unlink my psn from the email. So I will now be canceling my BF6 Phantom Edition pre-orderand won't touch another game from EA
