UPS lost an iMac that I sold to someone once for 3 weeks. When they found it, it seems the box had been opened for some reason and the shipping label torn off. When that happens I guess the package just sits in an empty where house until someone comes looking for it. Pretty ridiculous, in my opinion. The buyer I sold it to on eBay harassed me for what seemed like forever saying I somehow ripped him off. LOL I pointed out that it was UPS that lost the package not I. He was very apologetic once UPS fessed up to it and sent him the iMac.
I have had a LOT of issues with UPS, FedEx and USPS. Maybe we need to start a sparkle sisters shipping co. where we KNOW nothing will get lost.
