Insurgency - sorry for the new thread, but kinda had to

I know, there are some threads for leftover keys here, but I had the feeling, I Need to clarify something with this "throw out" because I created 3 giveaways of Insurgency, but had one "lazy" winner and - sorry for the small flame here - a "lazy" Supportmember, which of cause will not be named here.

I created those giveaways around 4 weeks ago, contacted the Support for a helping hand/what to do/a reroll around 2 1/2 weeks ago with the comment that the key will expire "soon".
First of all to the one who one the game. Tried to contact him via mail (10 minutes after the giveaway ended), about 5 days later, 1 key was not taken, so added the one with no insurgency via steam, first via Chat, than posted on his Profile.
After 2-3 massages and after he was online 2-3 times, i decided to send him another mail, still no Response. Again after a few days and the winner being online 2-3 times and trying to contact him with still no reaction I decided to contact the Support.

I got one quicker answer in which i was told to "proof" that i still have the key, trying to conact the winner etc. I wrote back how/where to send screenshots, but sadly never got a Response again for about a week now.
I'm writing this - officially - because this giveaway is still open with "awaiting Feedback" Status and i have no clue whether it's ok to "throw out" the key or not, but since it's expiring, I decided it'd be the best to make some ninja lucky bevor no one gets the key.

Some Feedback would be nice, otherwise sorry for wasting your time here ;)

In hope I didn't screw up by posting this - GO GRAB IT!
Cheers and enjoy!
