You can file a police report for this and look to press charges. If he does not have criminal intent (e.g. say this is because he is currently hospitalized and not able to communicate with you), it will not ultimately be a crime, but you don't know that yet; ergo, you can go to the police about what may well be a theft. You can also sue him to recover the load or at least its economic value, and he would be liable for it if he is at fault in any way in not making the delivery, even if he did not criminal intent. (Example: the delivery was not made because he stopped at bar while driving, got drunk, left the truck unsecured, and someone stole--in this case, what he did is not criminal, since he had no intent to steal, but it is still negligent or careless, he is still at fault, and he can still be sued.)
