Microsoft Store’s refund policy applies to purchases, including purchases made using Klarna One-time card transactions. Learn more about returning items you bought from Microsoft Store for exchange or refund. If you need to return your Surface device after your purchase, and are within the 60-day return policy for Surface, you will be refunded just as you would with a regular credit card. You can also alert Klarna of your return through the Klarna app, and your payment schedule will automatically be paused and your payment will be refunded to the original form of payment.
