Can't login for extended support

I found out UK users can get free extended support for windows 10, and I am not upgrading to 11, certainly not after they disabled local account installation. I tried pressing the button to get extended support but it is signed in with my old email (which got hacked and I no longer have access to), I entered the pin but it still sends a verification code to that old email, and it gives me no option to change which account is signing up for extended access. Is there any way to fix this and get the extended support with my newer microsoft account?
