Hey HarrisFFA,
Thanks for sharing the details about this situation you've been running into. If you no longer have access to the email registered to your EA account, and aren't even sure of the full email itself, the only way to recover this would be through support.
I definitely understand you've already tried this multiple times without any luck and you've been told to repeat the same steps over and over again. There is not a phone number, and any email options would go through the same support team, who would need to verify the same account information before any details could be updated.
The option(s) presented at the end of this process to create a new case would be the only way to get in touch with that team, unfortunately we're not able to make any changes for you via the forums.
If this is linked to an email you don't recognize, the one suggestion I'd have would be to create the case as a Compromised Account issue, rather than just under general login issues. If that email was changed, the support team would need to try and verify some separate details about the account that may be more feasible than trying the console verification method that already hasn't worked on multiple occasions.
