My parcel: LV305930859CN has been showing up as “Wuhan City, Export Swaps Bureau retained 2021-10-21 10:12” for 10 days. I have messaged the seller via WhatsApp, and they said “Rest assured”. And “not to worry”. I asked “Has the parcel has left China yet?” , and the seller replied “Yes, flight departure”
It should couldn't pass the check and is stuck there. In this situation, you need to contact the seller to reflect the problem and get a solution from the seller as soon as possible.
