i'm so sorry this happened to you as well.. was fedex able to do anything about it ?
that's exactly how i feel/felt - my privacy has been violated, i felt so much paranoia/anxiety knowing there was a possibility i was being followed, and a lot of people like to turn this into a "its just a materialistic item" story but i feel like its more than just a materialistic item.. my bf and i work hard for our money and to save it up to afford these items, and he gifted this item to me with his hard earned money - it wasn't even like i used the bag at all either, we had just purchased it, so that money was gone immediately.. and also the factor of our personal safety, my mind was running to all sorts of places the past few days about what would have happened if we were there when they were breaking into my car, or what if they actually walked up to us to attack us, etc.
we did file a police report and security guards ran through video footage - unfortunately the car's license plate had a tint over it so they can see every license plate in the parking lot except theirs..
i asked them if we happen to come across the resale market and find the bag, would they be able to help us get the bag back and they said its very possible (especially because we have a picture of the authenticity code/serial number thing) so i just thought it was worth a shot for people to keep their eyes peeled for me..
