The item it order from seller is something that can be take apart, when he receive the item, Some parts are disassembled for some reason. He can easily assemble them for use. But he insists that he don't need that function (the item can be disassembled and assemble ), so he insist the issue should be he received a damaged item.

If you don't need that function, just assemble the item,and never disassembled it in the future,that's it! How could that be a problem? You only need 3 functions,and the item can offer 4 functions, so conclusion is the item has problem? Not understand the logic here.

This buyer is dishonest, we think he just want to Take advantage of seller，when he gets the refund，then he will return around and assemble it quietly. Good job for him, successfully get a item FOR Free! Very Smart.
