Tough situation for sure. I really feel for you. In regards to the truck transport, it is possible that it left in a closed truck and then went onto an open truck at a distribution point. This is very common in the vehicle shipping business when you don't pay for a dedicated, enclosed trailer for the full journey.
As far as the service that you have received, it is very troubling. Get a lawyer involved if needed. I would bet that a small form letter from a lawyer will get the attention of someone there.
