Are they supposed to ask for the credit card details?
@BlahBlueKillYou2 This is actually to be expected when EA customer support is trying to verify ownership of an account. The account recovery form you'd submit instead asks for the same information. EA is pretty strict about restoring access to an account—people often try to steal other players' accounts with a bit of information—and all the extra info is part of the process.
As for handing over the info online, it sounds like the support rep was actually trying to match what you provided to what's already on file in the second account. Even if you didn't save your credit card info, EA would have the payment info in its database. So you wouldn't have added more personal information to your account.
The last four digits of your credit card number aren't by themselves enough to identify you or your card; think of how many credit cards exist just in one country. But since there are 10,000 possible combinations of four digits, it would be almost impossible for someone who isn't you to guess correctly, unless they also had your information, in which case you'd have bigger problems on your hands.
This is really the only way to get an account back when you don't have access to it, whether you've forgotten the username or can't access the email anymore. If you're not comfortable doing it, then the only alternative, unfortunately, is buying World Adventures a second time.
