Hi there. Emblems unlocked through promo codes will appear in your Collections under Flair > Emblems > General the next to you log into a character after redeeming. If you've already check there, which are you missing? Judging by the amount of codes you say you redeemed though, it's possible some may have been D1 codes, not D2. You can check by going to your [url=https://www.bungie.net/7/en/Codes/History]Redemption History[/url] and reading the descriptions of each item you redeemed. If any say, "Pick up your emblem at the Emblem Kiosk in the Tower.", that's a D1 emblem.
