First, the block making machine is fully automatic. During our communication, we sent multiple running videos of the machine. The video can prove that the block making machine is automatic, so our communication can continue. The machine is matched according to the customer's requirements and budget, and every detail is sent to the customer for confirmation before proceeding to the next step. Before paying the deposit, we also send pictures and videos of each part of the machine for customer confirmation. And the process is strictly executed in accordance with the invoice and Alibaba order we mutually agreed upon. After the machine is completed and the customer confirms that there are no problems, we contact his forwarder to arrange transportation. We have do nothing wrong, every step is under his confirm to go ahead. It's very unfair to us that he make such comments without using the machine, and even under the accessories we give away for free.
