My parcel with number RK527710149CN was sent from Suzhou on the 22 of september and now it went back to Suzhou (with stops in Being and shanghai) on the 20th of october, how is this possible ? It should already be arrived in the Netherlands.

3. I suspect your parcel was refuse entry in the Netherlands by the Netherlands Customs Office. Now the parcel is going back to the sender of the parcel.

4. Netherlands Post might be able to tell you more about your parcel or maybe your sender of the parcel.

Hope this help.
