missing package investigation
Does anyone know what the missing package investigation process is like? Here's the background info on my particular situation: I spent almost $1,100 on a new iPad Pro 4th gen that was supposed to be delivered today, 12 days after ordering. I was super excited to use the iPad for my schoolwork since I am in college, and worried about anything that may happen to it, so I stayed at home silently until UPS notified me that the package was delivered. At 2:37 pm I received a text that the package was delivered at 2:30 pm. I never heard anything. According to UPS, the package was left in front of my door (my address wasn't even listed, only the city and state), but there was nothing there when I opened the door, so I checked my mailbox, which was also empty, and saw the UPS truck driving away. Basically, the driver either left it in front of my apartment without even knocking or taking photographic proof, and it was stolen within 7 minutes (though I have never had a package stolen here); or they delivered it to the wrong address. In either case, it does not seem as though I will receive my iPad. I called Apple and they said that they would look into it and that I would eventually end up with the product that I paid for, but I guess I am just nervous what is going to happen coming up. I got an email that said Apple would notify me when they found anything, but there was no other information included. Can they somehow make it so that the exact iPad I ordered will not function, so if someone stole it, it is useless to them? Also, how long will it take before anything happens? If they never locate the package, they will send a new one, right? And if they do, can I require a signature so that the driver can't just silently leave it out for someone to take? I am so let down and shocked by the whole situation. I also couldn't find a good place to post this; the iPad pro 12.9 4th gen isn't even listed under devices and there is no option for ordering/delivery.
