If it is signed, it means that the goods are in good condition and there is no problem. Has nothing to do with logistics. If you sign for the goods first without inspection, the logistics company will not be responsible for the problems, and you will suffer. General courier companies are not allowed to inspect the goods, for fear of trouble, we can see that the outer packaging is in good condition. If it is fragile, it must be inspected. Refusing to sign means you don't want it. If you don't sign for it, you must return it.

There is a problem with the goods. If it is a quality problem, find the seller. If it is a transportation problem, find the courier!
