What should I do if the courier is irresponsible when I receive it and find it deformed?

if the outer package is damaged, you can refuse to sign, or ask for face-to-face inspection before signing.

you can sign for it first, but the courier number after signing is saved by yourself and not given to the courier company. Make sure that the contents of the package are intact before giving it to him. If the goods are found to be squeezed, deformed and unusable during inspection, you can directly claim compensation from the courier company. Just pay compensation according to the regulations on the website of the courier company.

when signing, you should first check that the outer packaging is in good condition before signing. After signing the receipt, you should open the package for inspection in front of the courier. If you find any problems, please ask the courier to sign and testify, and it is best to take photos and leave a certificate. So that you can complain.
