LoL what rly hmm,why did not you write anything, I would give you something else if it really is ?
I will say so all the keys that I issue are 100% non-activated, this is 2 such cases in a month, I apologize
i check now this key and actually it's a duplicate wtf, sorry I do not know how it is possible.
I need to talk to the store because it can not be.
Accept the invitation to friends on the steam and send you a list of games and you will choose something;)

Its ok, no need ;)
