I bought a key at this store, because of the false description and my false researches.
It was a key for a game I already had.
I immediatly contacted the support, and even showed my Steam Profile.
But they refused to refund me, because it was already disclosed by "email."
So they sent me the email with the key, after the purchase, and tell me, they cant refund me.
I recommend any other serious store, who refund you unclaimed keys.
But here you get scamed
