Grrrrrrrr I can feel your frustration
We used to have the same problem with UPS. I would be home, waiting for a package. Later in the day I'd find a slip on the door. No knock, no doorbell. It's like he just wanted to slap that sticky slip on my door and run off. I watched him do it one time, sprint from his truck, slap the slip on the door, ,and run back to the truck
So I complained about him and now there is a new, GREAT driver on our UPS route
I really hate it that someone can do a cr@ppy job, and still remain in that job, when someone that CARES could be doing it.
I hope you get your camera back.
