That is bizarre, especially if the package wasn’t damaged or didn’t look tampered with. I don’t believe I’ve heard of this sort of thing happening to anyone before. I really hate that happened to you man.
So whoever packaged that, tossed the receipt in, and just taped up the box and sent it on its way. Wow, that’s about as stupid as it gets. I would be absolutely irate. There’s no excuse for that oversight.
Geez man that’s unreal. What were they daydreaming about when they closed the box? Staring off into lala land apparently. Did you email them or call them yet?
This is a new low as far as that goes. There is just no excuse they could give to explain that away. How are you not looking down at the box, seeing inside of it as you close it up to tape it shut? Especially with no packing material? Just unexcusable.
