No Receive from my giveaway

Do you mean they haven't accepted the gift or they haven't marked it as recieved?

Did you email it to the winner?

Check if the winner has it in his/her library. If they don't, try emailing them again or contacting them.

If a week has passed since giveaway ended you submit a ticket to http://www.steamgifts.com/support

You can also try adding the winner in steam and ask him to click received.

Did you try contacting him?
