BungieStore (The part of Bungie that issued your code) is separate from the forums here. It's a different set of systems and people, and as such, nobody here on the forums can help you with your issue. If you tried to redeem the code and it says you already have it redeemed, and you've checked but the thing the code supposedly is for isn't unlocked, then the code you received was actually for something else that you do already have redeemed. You'll need to continue to stay in contact with the BungieStore Customer Support concerning the issue, as, again, the forums here can't really do anything to help remedy your situation. If you've not received a response in some time about your support ticket, you should be able to reply to the email you received. The 'check the forums while you wait on our response' is the automated email first sent out when you submit an issue, but in your case, checking the forums won't really help you any. If replying to the email doesn't work, you'll need to submit another ticket with the BungieStore Customer Support. If it's only been a few days, then I'd suggest trying to be patient, as the teams have to go through each ticket manually and things have slowed down considerably due to the virus issues. If it has been a full week or more, though, please feel free to reply to the email or submit another ticket.
