thanks EA_Pulsar, for the pointer on how to get into live chat. Unfortunately it was another 1.5 hours of my time wasted.
The first operator finally passed me to another one - both of which couldn't help. (We can't unlink or delete an account without verifying it. But the account doesn't get emails. But we can't unlink or delete an account without verifying it... over and over).
Issue - Its possible, when using EA Sports FC 24 on the PS4, to link the PSN account to an EA account using any random email address. The accounts get linked without the need to verify the EA Accounts email address. Now there is no way to delete the EA Account or unlink if from the PSN account.
Supports attempt to help (abridged version):
Me - We can't get into the new EA account as we can't get emails to it, so never receive the security code.
Support - I hope you are good today! As I understand that you would like to link PSN account?
Me - I want to delete an EA account so its no longer linked, so I can link the correct account
Support - Alright so you would like to delete the account? Thank you so much for the confirmation. We will ensure that your issue is fixed at the earliest.
Me - [edit: email address removed] is the account that is invalid. its a school account that does not receive emails outside of school
Support - May I know the reason to delete your EA account?
Me - (repeating the above multiple times in different ways)
Support - Thank you for sharing. You need to find the original verification email from account setup and complete verification.
Me - As said the account doesn't get emails
Support - Your email does not receive the codes because your email was not verified at the time of account creation. You need to go to your EA Account Security settings. Under Login Verification, click Turn On. We'll send you a code via the method you choose right away. Use that code to activate Login Verification, and you'll be all set.
Kindly check this article for more https://help.ea.com/en/help/account/ea-login-verification-information/#:~:text=Go%20to%20your%20EA%20Account,you'll%20be%20all%20set.
Me - we cannot log into your account. It doesn't receive emails
Operator then disconnected and passed me to someone else, and the whole loop starts again.
As well as all the above 2nd operator wanted to know the below for an account that has never been logged into or verified:
IP address (network where they play on)- [IP address]
Date of birth (provided during account creation)- [date of birth]
One purchase on account and purchase date (month/year)- [product purchased and date]
Last 4 digits of credit card- [last 4 digits]
Billing address - [address]
Phone number - [phone number]
So basically I'll need to create a new PSN account and the other one is screwed due to being linked to an EA account that we can't get to.
