Again, you sound as if you have no concept of the "real world". Not everything will always work exactly the way you want it to. There are a variety of reasons that a package may not be delivered to your door, among other things some of the more common are signature requirements, requiring customs payments, and the post office just not delivering to your house. The sender has no control over when you're going to be home, how your local postal system handles customs, or what the policies of your local post office are. It's more like a contractor not fulfilling your ever wish because it would be against the building code and then you getting upset about it.
