I'm really shocked at how CDKeys have been with me...
I bought an Xbox One code for £14.99. Tried to redeem it and it said it had already been used. CDKeys say there's nothing they can do as it wasn't used when they sent it to me. 2 messages later, they've stopped replying. Even when I open a new ticket, they don't respond.
Microsoft can't see where the code was redeemed, and Ubisoft tell me CDKeys is an illegal reseller so won't replace it for me.
What the hell?! £15 down the drain. PayPal are awaiting their response, but it's unlikely they will as it's now been 5 days.
