Terminating your account with ClickAndBuy
Remember that "Account Maintenance Fee" for ClickAndBuy? When you click "Register/Update Card Information and click "Unregister" under Square-Enix Account Management, tou are essentially "unlinking" your Square Enix account to use ClickAndBuy to fund your account. I actually tested it. Unlink, wait a few days, and I was still able to login ClickAndBuy. Therefore, your acount is still there on ClickAndBuy. If you forgot about it for a year, then an "Account Maintenance Fee" will start getting billed to your ClickAndBuy account.

Last but not least, goto the bottom, click Contact Us --> Registered Customer Form --> Fill the form in! (Subject: My Account, Sub-Category: Account Termination)
Ensure they email you back. I heard it takes ages :P
