If SHEIN missing package, here are the steps you can take:

Check your tracking information: The first thing you should do is check your tracking information to see if there are any updates or delivery exceptions. Sometimes packages can be delayed due to weather, high package volumes, or other unforeseen circumstances. If the tracking information shows that the package has been delivered but you haven't received it, then move to the next step. Contact SHEIN customer service: Contact SHEIN customer service through their website or app and inform them that your package is missing. Provide them with your order number and tracking information, and they will initiate an investigation. Protect yourself in the future: To avoid missing packages in the future, consider using a delivery service that requires a signature upon delivery or having packages delivered to a secure location (such as a locker or a post office box). You can also consider purchasing shipping insurance for valuable packages.
