Unfair people.

This puzzle is way too hard.

Did the winner activate your game? Maybe he just wasn't online during last few days. If you created a support ticket, just wait for answer. It takes a while.

Try adding him and asking him to mark it via chat, otherwise make a ticket with a screenshot showing the e-mail with the key you sent =/

Ty for response... I know my english sucks,but thads not the point xD. -but i traded throu steamtrading system, so i only got the chat pictured.

Ok got the picture but how do i send it to support there is no attach the file button..?

Maybe he just do not know what to do, He just registered on the site a month ago

Just point him to the rules, and dictate him what to do.

Support will fix it and mark it received once you give proof (you will need to wait though :s)

I had put in a support ticket a month ago regarding the same thing; a user did not mark as received, and hasn't been active on the site since winning my GA.

I don't think the winner spoke english very well at all, because all I got as a response was "thank you" when I tried to direct him to the appropriate steps.

Support eventually got back to me (keep in mind there's only a handful of them) and told me that they will have to put in a request to the admins queue and that he will take care of it. Though we need to have a buttload of patience because it could take quite a long time. To quote "Please be patient, as these requests can take him some time to get to."

Got it, i send the pictures now i have to wait and see.. Must say big thank you to all thad help.!!
