How to react? Won used key - no communication

If he ignores him, just mark as not recieved after the 7 days.
There is not much more you can do.

I say that you just wait the 7 days and if nothing report the guy/girl to steamgifts mods and let them handle the situation.

I know waiting will suck, but other then that there isn't much else you can do.

Okay, thanks guys. I just thought it was sad for both parts. The creator has already made cool giveaways in the little time he has been here and then suddenly he gets a "not received". But yeah, I guess my friend will just have to wait.

=)

Declare war!

That's what the last five decades worth of presidents here in 'murica would do anyway...

Call 911 , and send ninja cats to his house.

Also as everyone suggested , if you already tryed to contact him ... just w8 a week and mark as not received .

Also you mentioned that he made another GA for the same game ...
Mby he messd up the codes , or made 2 giveaways for the same game by accident ( happens quite often actually )

But still if there is no response after your atempts to contact him ... just w8 a week and mark as not received

are u talking about me? the description is equal to me ahahaha, but i dont ignore user xD

I had a similar situation. Won game, key was duplicated and tried to contact the creator but he didn't reply or accept my friend request. i just marked it non-recieved and never bothered again.

I have the same issue, but worse. I gifted a game to a guy by sending him the gift via e mail, but he didn't check it and I didn't receive my feedback. tried contacting him on Steam but he doesn't accept my friend request.
A private message system would be so nice to have in here

Contact winner of other copy of same game, say: ayy what yo key? If same, sue for fraud.
