Hello coned129.

Do you mean this giveaway in your ticket?

If key turned out to be already used you should not mark it as received, and instead leave not received feedback. Write to giveaway creator that key was already used, and they should provide you working one. Otherwise you will keep not received status to not risk suspension.

Right now you marked this giveaway as received, but don't have game on your account. So you risk suspension because of having inactivated wins.
