I am a Posta Worker who has seen and heard it all. If you don't use some sort of tracking, insurance, delivery confirmation, certification etc. when the package gets delivered, which it probably did, the person receiving the goods just has to tell you he never got it and there is NO proof of delivery, then your out the cash. If the carrier says he delivered it, the person receiving it just has to lie and say he got a package from someone else and that wasn't the delivery you sent, well your still out. You learn the hard way. I am not saying that everyone is dishonest out there, but to be on the safe side get Delivery Confirmation to track the package, especially if it has value. Don't keep your hopes up too high especially if from the time you mailed it until now is more than 2 weeks. You will probably never see that package again. Good luck.
