A friend of mine purchased a $300 razer gold card from Amazon, upon redemption i got the invalid pin code response…i don’t know what to do because I didn’t give anyone else the card and i am as well confused on why it wouldn’t work, i have emailed Razer gold and Amazon on this issue, Razer gold just gives me a loop of automated replies, while Amazon hasn’t given me a reply at all…please help because $300 is a lot of money.
