Is an item of clothing that didn't fit that I returned to the seller in China. It was sent on 17th March 2021, and arrived in China on 28th March. It sat from 28th March until 11th of may when it arrived at facility. It was then marked "Import stopped by Customs (Inbound)" on 11th May and has not moved since. The tracking number now says "expired". What can I do to get the item to be delivered to the seller so that I can get a refund?

To whom may concern:

I’ve posted a parcel from uk to China, uk Royal Mail to China EMS 26th of March 2022, it has been over 45 days without any update. Please have a look into details for me thanks. RN602327758GB
