Post to China from UK.

Hi, I hope you can help.

I returned an item from eBay to China, I posted it on 22nd January by Royal Mail in the UK. They estimated that it should take 7-10 working days for my parcel to arrive.

It is over 1 month later, and the seller claims that they have not yet received my return. Foolishly, I did not pay for tracking when I sent it, as the seller begged me not to in order to keep costs down.

I am pretty sure the seller is lying to me, and has actually received my return already. But I want to be sure. Can you tell me, what happens if an item can't be delivered? Where does it go? Would they send it back to me, as I did mark it with my address also? Or are they kept in a warehouse somewhere? Is there anyone I could speak to who could confirm whether my item was delivered or not?

I really have very little hope of ever getting my refund, and I realise I should have paid for tracking.

Hope to hear from you soon.
