What do you do if you do not receive your gift?

I understand your frustration but it happens, people sometimes don't understand how the site works. Keep entering giveaways, you'll eventually win.

My first non received win was a Saints Row IV pre order I won with 3020 entries. Crap happens. Deal with it. You have gotten more out of this site than you have given (two freebies and attempts at giving away free betas have been your only gifts).

Except the whole point of the site is it's user-made giveaways. If the person doing the giveaway doesn't deliver, I get it, that sucks, but you're not guaranteed the prize just because. You might as well say it's not fair to not win at all when you enter into a load if giveaways.
Anyway, it's not like you lose anything by not getting it. You're no worse off than before the giveaway.

look at it from diffrent perspective, you won twice as much as you given away, whatever happens with this GA you can still consider yourself really lucky ;)

While I get that we're not supposed to call people scammers, we're not dealing with a terribly difficult concept, here; you start a giveaway, somebody wins, you give them the game. It's pretty straightforward.
