How to get EA to actually do something?

Hello!
So my Microsoft Account email was changed about 5yrs ago (gamertag is still the same)

My EA account no longer reflects being attached to a gamertag for xbox, and when I try to re-link it.. the EA site references my old "@live.com" email, which no longer works as I changed my email address to "@outlook.com" due to the @live.com getting a ton of spam thanks to a data breach.

Anytime I try to chat with EA about it, they try to email the @live.com address (my EA login is my gmail btw), and the @live.com no longer exists.

How can I actually get EA support to understand i'm not trying to recover my account, i'm just trying to re-link the SAME gamertag that's now attached to an @outlook.com address.

It's a 20% chance I can even get the option to chat with a rep, and when I do.. they just tell me there's nothing they can do? EA's systems should be smart enough to see the same gamertag is attached to the new MS email.

Any help would be great!
