Dear Khun James. First of all, I would like to thank you for your order. As you have informed through this product review, I would like permission to coordinate with the relevant department to investigate and take care of you in the next order. So, I would like to clarify the conditions for receiving the product or returning the product to you a little bit as follows. 1. You should inspect the product before signing to receive the product. While inspecting, if problems are found such as the wrong model, wrong color, incomplete quantity, or damage, etc., you can refuse to receive the product immediately. 2. You can inform problems with claims - returning products in all cases at Call Center Homepro 1284. first, every time so that the staff will take care of you. This is currently in progress. However, if you would like us to take care of you in any matter, you can inform the staff directly. To apologize for your inconvenience. Admin
