What should SF Express do if it loses its headphones and wants to settle with me?

If you can't reconcile, SF is too bad, you should let them bleed. Anyway, the responsibility lies with them. My situation is similar to yours. I gave them a set of mobile phones with a price of more than 2,000 yuan, and they never informed me. It took nearly a month to ask for two days and said it was lost. I don't know where I lost it, and I lost six times. Moreover, they said that the "lost" in the terms is a special word in the express delivery industry. Lawyers know that asking their employees is a typographical error. Think about things that their employees don't know.
