Hello Quinn foster,
Welcome to Microsoft Q&A forum.
The purchase of Game Pass subscription can be refunded; however, it will depend on the time of the purchase, location and type of subscription.
The link that the AI assistant gave you usually are made for digital games refund request, they don't usually handle subscription refunds. So if you cannot find the purchase there, please try to contact Xbox Support or check the order history of your Microsoft Account to see if you can request a refund there.
Thank you for your understanding.
