I finally received my code today.
I've send several mails to my gamestore, saying that they should be given codes from the publisher.
They said that they only were given a small amount of codes and I just should be patience.
Which ofcourse is weird, because if they don't have enough codes, why should I wait.
Anyway the next day I already got my code.
So I don't know who's to blame here. The gamestores or Rebellion.
Don't fight a battle if you don't gain anything by winning.
