Hi, i wanted to cancel a pre-order that i have, the game will be released on oct 25th but i changed my mind about getting it. How can i do that? i tried contacting the seller but just in case they don’t respond, what can i do?

You can contact support by emailing support@gameflip.com. We’ll be able to look into the particulars of this transaction and possibly message the seller on your behalf. Thanks!
