I had to contact customer support to get my Treasure Isle DLC code for Risen 2 and more recently, I received an e-mail saying that my Darksiders 2 key was available when in fact it wasn't available until a day later.
This is true. What's also true is I've cancelled the purchases of those games - not used the key - and asked for a refund explaining why and they've had no problem doing it both times it's happened so far. Best bet is just to check in on the forum to ensure the keys are immediate.
