He has 1 week to activate the game and give feedback.

Try to contact him via mail / Steam chat.
To see the contact information, click on the "Send Gifts" / "Gifts Sent" link on your "Created giveaways" page.

Edit: so far both winners of your 2 giveaways gave you feedback, so I don't see your problem, please elaborate.

It a send Now the feedback

if you sent it through email and he still clicked not received try contact support. or try contact the person in steam ask him why he clicked not received.

He doesn't have the game in his library... In this case, you'll need to contact SteamGifts support with proof that you sent the guy the game (Frozen Synapse)
