guys, if anyone had this issue can you please help me.
a month ago a bought an 1080ti to a friend, they send me the code later then the card came and i installed and follow the steps to redeemed and bamm!! "The coupon code you have entered has has already been redeemed" i try again and the same. contacted amazon and they told me that i need to contact with Sony, yes Sony and they gave me the us.playstation/support page and my face was WTF, and told them why and they said they where the publishers and rapidly google it just to be sure but no of course they're not, Activision are the publishers and i told them that and they just said ok contact them and they provided me the support page and of course you cant have support to destiny regarding PC platform.
now today i contacted nvidia explaining everything and they just told me to contact amazon because they provided me the used code.
so... i dont know what else i can do guys. if you have any suggestion it would be appreciated.
