Try contacting EA Customer Support. They have a Live Chat feature in their support site. I got my Dead Space 2 Ser Isaac Armor code immediately during the session.
I haven't got the codes yet, unfortunately...
I hope this will be resolved until the game unlocks in Western Europe.
Edit:
OK. A chat with support revealed that I'll get the codes once the game unlocks in my region (Germany).
Thanks for the heads up on the support chat feature.
I did spend an hour with them in chat. They could only give me 3 codes and no explanation for WHY the DLC codes were not sent.
I want ALL of the items I paid for with my pre-order, not just a few. I hate playing this game without The Black Emporium.
BIOWARE, why haven't I heard your voice in this matter (and I am not alone). I'm tired of dealing with E.A. It is your game so please find some resolution for me (us).
