If you purchased the code directly from us and created or upgraded a WildStar account with it, that account will be permanently closed. This means that the email address you used for that account cannot be used again for a WildStar account. If you decide to want to purchase the game at a later date, you will need to create a new NC Account using a different email address.
If you purchased the code directly from us and did not add it to an account, the unused serial code is permanently disabled.
If you purchased a code from a different online or local retailer, you will need to work directly with them.
