Don’t purchase Xbox reward playing cards from Amazon

Yesterday I purchased a 50$ xbox digital code utilizing an Amazon reward card, after I would kind within the code I might get a message saying “this code has already been redeemed”. I contacted Xbox and Amazon assist and so they mentioned I needs to be notified of additional information about this occasion. Proper after, I purchased one other 50$ reward card code anticipating that it was only a fluke, anticipating that this challenge would by no means occur once more. Quickly after typing it I bought the identical response. I’ve no clue as to whether that is Amazons fault or Microsoft’s, all I can say is that I’m mad asf. In the intervening time, I wouldn’t purchase Xbox reward card codes off of Amazon as a result of there appears to be an enormous challenge with the validity of the codes.
