My Daughter purchased a key from them on the 10/10/21 when we tried to activate the key it said it had already been redeemed she contacted cdkeys support they told her that she was only person the key had been sent to and they could see it had been redeemed (all clearly lies as we found out). They advised her to contact Xbox support. We did so and they were very helpful and informed us the key had indeed been redeemed on the 02/10/21 a full week before she bought the game from CDKeys. We submitted a screenshot of the chat with XBox support and a screen shot of her account proving we had not used the key. They told us to wait another three days which we did now they won't reply to our messages and have not issued a refund or a replacement key. We are now going after them for the money. I have bought codes from them in the past and it's been ok but clearly they're up to some dodgy practices and it's probably 50/50 weather the key they give you works or not (or is stolen). My advice don't buy from them there is a very real chance you will get scammed.
