SF doesn't want to send it after picking up the courier at home. Will it be lost if you don't return something and don't answer the phone?

No, according to the inquiry of SF Express official website, the courier's pick-up process is to pick up the pick-up and put it at the outlet, which will be kept by the outlet staff. If SF Express doesn't want to send the courier after picking it up, and it won't return anything, you can contact SF Express's customer service phone to ask for a return of the courier, or you can contact the branch staff to pick it up and ask the branch staff to arrange for the courier to return the courier. Therefore, SF doesn't want to send a courier after picking up the goods at home, and then don't return things, don't call, and don't pick them up.
