missing trailer at Amazon facility

We are delivering to an Amazon facility and they tell us to drop trailer in a dock and come back. We did as instructed and dropped the trailer last night and we come back to pick up trailer this morning and its not in the dock. We looked all over the facility and they do not know the whereabouts of our trailer, at least at the moment. This is a new Amazon facility in Hazel Park MI. So what is the protocol in a situation like this besides filing a police report and contacting my insurance company. The broker on this load is telling us to wait until monday because they are the weekend crew. If they do not find out trailer who is responsible the broker, Amazon or will this be something our insurance pays for? I am wishing i had invested in a gps tracker ARGH

 

Thats what they are telling me is that another carrier probably took it and that it may be on its way to Indiana or Illinois somewhere. How is that ####ing possible it has my company name right on the nose of trailer. They are pleading to not contact the police just yet. She also tried offering me another trailer, but i do not want another trailer, i want my trailer! And who is responsible if who ever took my trailer bangs it up or takes my new tires?

 

I understand you need an empty but how do you take a trailer that does not belong to you makes no ####ing sense
