How does this happen?

You should have contacted support :/

wow, this seriously sucks :(
please contact the support, they should be able to help you

Contact support as Warrant Officer suggested.
Yeah, its crappy that you can change from received to not received forever.

You can mark games "not received" starting one week after the giveaway has ended. I can go troll Yatterman from five months back I should be so inclined.

Awesome I will give that a try. Its dumb because we are talking a $5 game here $2.50 during the sale week I would just buy another copy if thats what it took. Oh well thanks for the help.

Too bad it happened to someone as generous as you. :(

Omg, this jerk is a Pole... What a shame.

Look at his game recommendation, I can't even translate it properly to Eng, but it's like " fucking great fucking game"

One of his nicks was:

• "i like to fuck little children"
• "metin 2 the best game"

@Dangeross: don't forget to add more information about his behavior, when reporting him.

It's a shame that this happened to someone as generous as yourself. On the bright side, this should be easy to solve. Just contact support.

Support was very fast and helpful. Thanks everyone for the advice.

the button "not received" is disabled until a week (i think) after the giveaway ends, but you can also click it when you previously clicked on "received". your winner was just being a dick.

The worst of all this for me, is that I entered that giveaway and I really wanted the game :'(
