Refunds on Bundles\n\n You can receive a full refund for any bundle purchased on the Steam Store, so long as none of the items in the bundle have been transferred, and if the combined usage time for all items in the bundle is less than two hours.

You can request a refund on your Xbox order history page. Select the relevant item and choose Request a refund. Provide the reasons for your request and select Next. If everything is correct, select Submit.
