Im guessing you didnt notice the item was delivered to (name) at this address , it will now become a police matter, one of theft by (name) at this address ,proof of delivery is the responsibility of the carrier , all carriers from amazon to dpd ,non delivery, loss or damage is a dpd insurers issue, as it is with every other carrier , and allow me to reiterate i speak from personal experience as an ebay seller ,its the reason i insure all deliverys
