Make sure the tracking is on the item in your Sold section
If it arrives and says Delivered or attempted delivery then you would win any not recieved dispute.
If the seller wants to return once they receive it then you wait until they request a REturn.
You have No returns accepted so could refuse. The would not be able to open another disptue once one is close.
They may not be honest and open a Not as described dispute where you have to send the return label
if they do that then you would have to follow the dispte
Dont do any thing and certainly do not refund them until it is done through a dispute.
All problems are through a dispute.
