Take some deep breaths. It is possible that the rest of your order could be coming in a second packet still, you may see it in a day or two so maybe just keep waiting to see. It does sound like your parcel really got the run around.. so I 'd probably be concerned too seeing its been opened so much. Ive had a Australia post postal issues in the past week (not from there).. a neighbour showed up very early the other morning with one of my parcels. It had the right address on it but the postman delivered it to the wrong number. Thank God that neighbour was honest and brought the parcel to me. I spoke to the postman the next day about the wrong house delivery but he said there are others too who do the deliveries.
