Dear Khun Paul. First of all, I would like to thank you for your order and your review. I would like permission to coordinate your matter with the relevant department to contact you for information, pictures, and product video clips to check and take care of you in the next order. While this is in progress, the staff will contact you directly. If you would like us to take care of anything, you can notify the staff. So, please allow me to notify you of the inspection of the product a little. While inspecting the product, if you find a problem such as the wrong model, wrong color, incomplete quantity, or damage, etc., you can refuse to receive the product immediately and you can report all cases of product claim-return problems at HP Call. Center 1284 every time or you can take the product with the complete package and payment receipt to the HP branch near you so that the staff can inspect and take care of you. To apologize for your inconvenience. Admin.
