I live in Australia and often order items from the US which are delivered through the Global Shipping program which makes it easy for US vendors to manage the international shipping -

recently I purchased an item which Ebay shows as delivered - it hadn't been delivered so I checked with Ebay customer service who said I should check with the carrier who was Fedex 

I had the tracking number from Fedex (which Ebay supplies)  and contacted Fedex - they advised me that the item was "delivered"  to the Australian Postal Service who wold deliver it to the final destination - therefore they classed it as "delivered"    and it shows as signed for by the final recipient on the Fedex site -  clearly the final recipient has not signed for  the item   as it has not been delivered

I have an email from Fedex confirming this arrangement   - So this represents a significant glitch with the Global Shipping program - Ebay has documented  evidence that the item has been delviered and signed for fhen it has not 

An me the buyer has no direct relationship with the intermediate arrier Fedex and no wa of finding out what happened to an expensive package 

I think this is an unfortunate system falilure - it is still possible that the Australian Postal system may deliver the package - but if they don't it would seem that this is my risk  

I wold ask that Ebay look at the reporting of  the use of multiple carriers so that items are not reported as delivered when they are not   - on the whole I think the Global SHipping program works well and Ebay should be commended for organisaing it but this issue shows up a regrettable oversight in the tracking and shold be fixed
