Friend bought a game code on promotion and it's missing...

Friend bought a game code on sale long time ago. He wanted to use it now after finishing the trial but the link from his email is going to the sqex front page. Even if he's logged in, the registration code doesn't show up.
He played before DT and the trial then was up till SB so the code should include SB, SHB, EW.
Has the link expired? If so, what about the money he paid?

It should be under Orders > Order Details in his account if he bought it from the SE store.

Friend checked it and it's empty so it's as if he never even bought it. He has an email delivery though
