Hi princesskurtt,
This sounds like the 'Know Your Customer' process that EA Help use to confirm account ownership. Since accounts can only be amended when account ownership has been confirmed, if you're not able to pass this successfully then they won't be able to change anything. While I do agree that this can be inconvenient, it is for security reasons to protect data, payment details etc.
Unfortunately, all I can really think to suggest in this case is to try again with EA Help as they may be able to clarify the information they're asking for.
