After your refund is processed, the refund amount will appear on your payment schedule within 3-10 business days, and your balance will be updated.
If your refund is less than your total purchase balance, then it might not lower your next payment. Instead, you can expect fewer payments, a smaller final payment, or both.
If your refund is more than your purchase balance, then the difference is returned to your original payment method within 3-10 business days.
If your order is made with monthly payments, then the paid interest isn't refunded. Interest is the cost of borrowing, and isn't refundable.
