EA account help

I have had my EA account for almost 20 years. When I made it I was very young and I used my mom’s old email. That email is now deactivated and I am trying to change it to my current email. Also, I forgot the password to the EA account due to the age, but I always log in from the Xbox gateway and that’s how I got to EA support. I tried to submit a ticket but the “resume case” button is broken on the ea help page. It just takes you to the topic help page. I have yet to get a response. Can anyone help me get to the right place/support.
