The courier only sends text messages.

Express delivery means delivery. As long as the goods are delivered on time and in good condition, his work is finished, and the quality has nothing to do with him. If there are quality problems, you can contact the seller to negotiate a return. There is no reason to return the goods for 7 days now. If you want to return the goods, you can ask the courier company to send them back. If there is freight insurance when shopping, the money from the freight insurance will be returned to your account, and the excess will be replenished by some ordinary merchants.
