In this case, you can exchange the order/product by mail us on firstname.lastname@example.org with your order number and all details.
The customer will get 100% credit when the customer doesn't want to exchange the product and cancel the order within 24 hours.
After the 24 hours, the customer will get 85% credit (15% credit is for order processing charge).
The customer can use that credit in the next order.
Please note that, returning a product without email notice and without approval from us WILL NOT qualify for a exchange. And the customer's request will be automatically rejected.
Unfortunately, an order cannot be canceled/exchanged once the item has been delivered to you.
In any of the above cases, you can get in touch with our Customer Support for more information
