Wrong email for account

I have the same issue for madden 20, I have 2 Xbox ones consoles. One allows me to play madden but the new one asks me to do a log in verification but the email it has is about 17 years old and I don’t have a way to access it. I even contacted the company who bought the email server many moons ago and they said the account doesn’t exist on there servers anymore. I have made several cases to EA only to get the same no help reply. Saying with the information I provided we aren’t able to help with your request. No matter how much info I give them with (picture proof) they just close the case and I’m stuck not being able to play the both systems. It’s beyond frustrating because EA has no technical support call or chat system. It’s just file out a form and you can’t explain in writing what needs to be discussed on phone or chat.
