Hi, Dear, You paid on December 20, 2024, and confirmed the equipment test with you on December 24. Our goods have been sent to your designated warehouse on December 31, so there is no problem of late delivery. Secondly. We have tested the machine in advance before delivery, and the test is normal. We sent you a video for confirmation. You cannot make us bear additional international costs just because you change the scope of transportation and services. It is unreasonable for us to slander the quality and delivery time of our products because we have not met your needs.
