Returns and refunds on gifts.

If the refund is approved, it will return to the gift card that was used.

It might take a few hours for new purchases to appear in your list.

If you don't have the order number, wait a few hours and then check back again (you may need to refresh the page).

If you still don’t see your purchase listed after 24 hours, return to this page to continue.

My name is Loren. I'm an Independent Advisor, and I'll be glad to help you today.

Microsoft has a dedicated team that handles all refund requests though, you can request one through this link:

To get the order # of the item, you can check your order history page at https://account.microsoft.com/billing/orders

Yes, I tried looking for it, though my purchase doesn't appear on the available list.

That game is not available for PC through Microsoft. So unless there's something else you'd want to use the gift card for, she can try returning it. Gift cards usually aren't refundable though.
