hi i won this game but i couldn't use it because somebody used the code. Can you help me?

Hey man,
I'm The PAZAZE Dragon, One of the admins of a group called Quality Games Giveaways (QGG).I've noticed you as someone who is active in SteamGifts, and likes to giveaway (and win) high quality games. And I think you will be a good fit for the group.We started the group, because I didn’t like the fact that any decent game in SteamGifts gets so many entries, you have virtually no chance of winning, and the games you do have a chance to win, are not very good. In our group, all games are at least of decent quality, and you have a good chance to win each one.You can see a sample of the games given away in the group here
And full group rules can be found here
Let me know if you're interested.

Cheers
