I have recently just cancelled my trade with somebody, (with me being the seller) and I was just wondering, what if the buyer doesn't cancel too within 6 days? Do I get blacklisted or something? Hopefully my buyer will canel aswell or else I'm not sure what to do.
No, not blacklisted, but you will receive negative feedback for "Game Not Received" because the buyer is under no obligation to cancel since you agreed you were going to ship your game. The buyer is in full right to leave a negative and for future reference, only agree to send a game out if you are actually going to.
nothing will happen and you will continue the trade like you were supposed to in the first place,of course you didn't word your question very well,.
