Gotta love it when shit like that happens. At least in the end you will have an even better machine than the one you ordered.
Last week something kind of similar happened with my wife. She ordered a laptop purse and the online tracking said it was delivered. I got home from work and nothing was on the doorstep and a note she had left for the driver was still on the door. There is another place in our complex that has the same number, but is on a different street and building #. Out of curiosity I decided to check there and sure enough her package was waiting on their doorstep. It said right on the package what building number it should go to. I've been meaning to go talk to them, when they are home, so they know if it happens again.
