Hey, I ordered a package on 20th December (Over 1 month ago) to the UK

When I check the tracking for my parcel (LZ578653088CN) - It keeps being dispatched from the Office of Exchange in Shenyang, and then being returned the following day.

Could you please check what is happening and why the parcel keeps being returned? If things are progressing, I am happy to wait, but if the parcel is stuck I would like to request a refund from the seller.

Thanks!

Here is the latest tracking info:

I wonder why the status on my parcel is stuck at "Dispatched from Office of Exchange Shanghai" for 6 days now? Is it on it's way to Sweden? It is sent from China to Sweden.
My tracking number is LZ196912110CN

Hi, my package LY475518421CN has been stuck at dispatched from office of exchange for 1 week now. Is it sitting under a pile of parcels in another processing location? Or is it on the way?
