Hey bro, I am the winner. Thanks. But the key you gave me has already activated. I can't activate again.

me too

I just won them some hours ago in another site from a random giveaway, I had no idea that they may be fake O.o

EDIT I already sent a support ticket to the specific site about the issue.
EDIT 2 They answered that they cannot do anything about it, so I will add you both on steam to sort things out.

Thanks your gift, bro. Have a nice day.
