Did the buyer confirm the receipt and payment? If there is no one who can apply for a refund, if you insist on not returning or can't discuss it together, he can apply for Taobao customer service intervention, so that you will fall into a commercial dispute and your reputation will be affected;
Did the buyer give you an evaluation after confirming the receipt? If you don't have him, you can give you a bad review, which will directly affect your reputation, or apply for Taobao customer service intervention, so you are a commercial dispute;
If the transaction is completed, he can go to Taobao to complain about you, and you will be in trouble (if it is your problem).
2. What if I didn't send it to others? Write a fake logistics number when you deliver the goods. Leave me another mobile phone number of the logistics company, hehe! How do customers solve it? What if I don't give him a refund?
A: The answer is the same as above.
