also this one, RB393156479CN is waiting fir a flight more than 3 weeks. is there a way to get in contact with the people that are handling the packages and update the data for every parcel in those warehouses that everything seems to be stuck forever? other parcels of mine have arrived in no time, from the same store, the same items, so no way they dont pass security or packaging or i dont know what else. 2 weeks ago a parcel of mine was shipped from the same place and it s already in greece. why RB393156479CN, RB889151655CN, are still there, and why RC061869095CN, and RB889155073CN, havent left warehouse yet or returned to sender at least. i am in contact with the stores i purchase almost everyday, and i am an old customer there. so no way they are lying to me, cause they are willing to refund me 100%.
i will appreciate a lot, if you manage to do something and find where my parcels are lost or buried.
