The rate of Blizzard Authenticator restock within our Online Store, Zengetsu, is dependent on the rate of production—a facet over which Blizzard Entertainment does not possess direct purview.
While you've my utmost apologies for any delay your friend has experienced, please know that we regularly provide additional supply as it becomes available to us. Encourage your friend to check with our Online Store frequently. Perhaps during the morning hours, if possible, as this is when many fellow players have noted successful purchase. :)
In the meantime, refer your friend to following post. While the possession of a Blizzard Authenticator will greatly bolster one's security, it is not reason to forgo lateral measures.
Most specifically:
Q u o t e:
Along with account names and passwords, it's possible for registered email addresses to be compromised, as well. Because of this, we encourage you to update your registered email address as quickly as possible to prevent repeat compromise.
It's also important that you do not simply re-register an old or currently-active address. Any email address which may have been in use at the time of compromise may be at risk, so it's best to set up a new one from a computer you know to be secure.
When selecting the username and password for this new email address, ensure that these variables do not overlap with that of your WoW account or any other login type (guild websites, Facebook, MySpace, etc). Once this address is registered to your account, do not use it for anything else: no additional registrations, no guild websites, no newsletter sign-ups, et al. Keep this address isolated.
Should you be unable to register this new address yourself, please contact our Billing & Account Services Department for assistance.
If either you or your friend possess any additional questions, please let me know. I wish both you and he the best. :)
