Deleted original email, cant get help with support

I still actively use and access my EA account through my linked Xbox account and have had continuous access to it for years. However, the original email connected to the EA account was deleted a long time ago and cannot be recovered through Google anymore. Because of this, I cannot receive verification codes needed to update or change the email address on the account.

I have already contacted EA Support multiple times and tried account recovery several times. I provided information such as:

Xbox purchase history, linked Xbox gamertag, previous account details, approximate account creation period, other information I could remember

The problem is that the account was created back in 2019 when I was younger, so I cannot remember every exact detail originally entered on the account. Support keeps telling me that some details are incorrect, but they do not specify which ones.

I can still fully access the EA account through Xbox login today. The main issue is only the inaccessible email address.
