Is this a GSP item?
Then, your responsibility ends, with tracking showing delivery to the UK hub at Lichfield.
If a case is opened then enter that tracking number if it shows delivery to the hub, the case will close in your favour, and if the item is lost eBay / GSP system will refund the buyer.
Same applies, if the delivery details eBay sent you for the item, showed another UK forwarding Company.
