Unable to delete EA account and be forgotten

I'm unable to open new support cases and so unable to have my EA account deleted. The button to open a case is not there.

Context:

I've been trying to get my EA account deleted and all of my personal information removed from EA databases. (right to be forgotten)

I found EA's help article on this topic here: https://help.ea.com/en/help/account/close-ea-account/#right-to-be-forgotten

The link in that article takes me here: https://help.ea.com/en/solutions/?product=ea-account&category=data-privacy&topic=delete-ea-data so I proceeded to create a case to do this.

The advisor said they couldn't do it but they would escalate it to another team who would email me at some point (couldn't tell me when). I did receive an email from EA support containing a link but by the time I checked the email and clicked the link it had expired.

When I tried to do this again by opening a new case the 2nd advisor I spoke to said they couldn't help me unless I provided them with the email address that I used to create the account. They wouldn't accept the email address that is currently linked to the account and is the one I used to log in and raise the case. But my account is 13 years old and I don't know that original email address anymore. I changed the email address on my account years ago and have been logging in successfully with it ever since. I was logged into my EA account which is how I was able to open a case in the first place and there is only one email linked to my account and it's my current email which I can access.

This was surprising as the first advisor was able to help me using my current, existing, linked email address.

Following a useless conversation with that 2nd advisor who would only use stored responses that made no sense in response to my messages I closed the case and tried to open a new one with a different advisor but now the button to open a case has disappeared and I'm unable to open one.

Now what?
