Dlc for Mass Effect 2, no promo code

Hi!

I finally got around to buying mass effect trilogy on ps3.

So now I'm on the second game, naturally I want all the dlc's. But appapparently i need to enter my promotion code. I got no promotion code in my box. I bough it new and sealed.

I tried registering the game on bioware but the UPC code doesn't work, so no code from that page either.

I've tried googling the issue but no solution.

What do I do?
