I don't have access to an old Email

Hello the email address I originally used to setup my EA account is no longer available to access. When I enter the old email address on the EA portal it just keeps telling me that it's sending a verification code to the old address that I cant access for the code. I reached out to the email provider & the company no longer supports access to the email listed on my EA account.  I need help from your EA support team with resetting my old email to my new and current email or I need my old account deleted to break the link with my xbox live account so that I can create a new account & relink my new EA account to my xbox live account . Please help I'd like to have access to EA for the new Battlefield 6.
