Account softlocked

My EA account (made in 2019) is linked to an email that was deleted around 4 years ago, I am able to access the account at times through my Xbox connection, however I want to change the email the EA account is under,

EA are refusing to do this by any other method other than the recognised device method, which I have repeatedly tried to accomplish, alongside being on a chat with an EA advisor whilst attempting to login and them force sending a prompt, which didn't work.

so now I am stuck, I have a 7 year old account which has had a fairly large sum put into it (mainly apex) which I could potentially loose any minute because EA refuse to verify that it is my account another way.

Any advice? EA advisors seem to be stuck on the recognised device no matter how many times I have told them it doesn't work, and I cant seem to find a way to escalate the issue further, or have any other option then to "deal with it"

apologies for the rant, spent 16 hours total going through ai chats and conversations with front desks who clearly were not trained or could actually do anything.
