Thank you for your contact. Postage costs to return the goods will be approx $50. I will see if I can do something about the missing items myself, so this time please make a partial refund of $100.
Thank you for contacting us. Considering that shipping cost will be estimated about 50$, I would like to take another measures in place of the fault parts. It is fine to refund $ 100 as a part of the product.
