All express delivery companies now allow customers to sign for goods first in order to avoid risks.
The only good solution:
1. Sign for receipt first and then inspect the goods.
2. After signing, quickly put the courier order into your pocket
3. Let the courier witness the inspection together, because he could not get the order and left. No, if there is no problem after inspecting the goods, return the order to him. If there is really a problem, ask him to sign to confirm what the problem is, and then sign.
4. At the same time, under the witness of the courier personnel, call the seller to inform him of the problem with the courier.
The rest is a matter of claims from the seller and the courier company.
