When the courier delivers the goods to your residence to meet you for inspection, you should carefully check whether the goods are in good condition. If there is no problem, just sign the express delivery form. If it is later found that there are other non-human problems, but the receipt is not confirmed on Taobao, you can contact the seller to ask for a return and discuss who is responsible for the return postage. If you confirm the receipt, you should patiently explain the problem to the seller. Perhaps the seller will allow the return of the goods after confirming the receipt, but in this case, you have to pay the postage for the return. If none of the above works, you can contact Taobao customer service, and the third party will handle the problem.
