I am sorry that you for the issues you had during transport and installation. Firstly we accept the mistake during communication and agree for reasonable compensation. But we don’t accept any black mail by bad comments. As a responsible vendor, we won’t fraud any client. The mistake doesn’t worth $10K. We have sent details to you to check before packing and did video call many times to improve as what you wanted. Alaso we accept inspection before shipment. The packing was well done and showed you before shipment, we offer EXW term. So you arrange the shipping by yourself. The damage during transport should be beared by the shipper, and we don’t think the damage is during transport because you should inform us as soon as you receive the goods. For installation, The window and doors are customized products. The installation should be done by professional installer, we understand you have a little problem to sort out the stuff because you are lack of experience. we have been helping
