Cancel Payments
You may cancel a payment if the funds have not cleared. If you want to return the funds irrelevant of it's payment status you can use void payments.
You cannot partially cancel an order, if you want to return a fixed value of the order value, you must wait until the funds have cleared and then process a refund
