I placed an order from a company a few days ago, and have been tracking my package. At about 11:00 AM today, I tracked my package and it said it had been delivered at 10:00 AM. I was home all morning and didn't see or hear the delivery. I went outside to check. No package. I checked around the back door. No package. I even took a walk down the block to see if it was on a neighbor's porch by mistake. No package. I contacted FedEx and they said that records show it was delivered at 10 AM. I insisted that the package was not there, and they said they would put a trace on it (contacting the driver, and asking him to trace his steps in case he left it somewhere else by mistake) but that will take 24-48 hours. Has FedEx ever lost one of your deliveries? If so, did you file a claim? I contacted the company where I placed the order, but haven't heard from them yet. This is a 25 pound box and is $300 worth of books, so it's not a small or light package. I hope it's found soon!
