Ebay won't do anything because the seller followed protocol. For items <$750, all that's necessary for seller protection is tracking showing delivery. (SC isn't required and unless a carrier requires it, it's not recommended unless the item is $750+)
Ok I see. Not really an ebay person (had bad experience with their customer service or should I say lack thereof), more of an
amazon person.
Without being harsh, the holiday season is prime time for package thieves and buyers who expect deliveries, need to have a secure system in place to either be there to accept the item when delivered, have packages held at post office/UPS/FEDEX/etc. or otherwise do what's necessary to avoid theft.
