I'm not sure you could pin point one individual, that would most likely be a lost cause. You would have to sue the whole company of UPS. As for the snake living, I have heard stories of them living through worse, they are just sick. As for your breeder, I think you have found one that really cares and is going above and beyond as it is not required for them to give you a refund if the snake arrives dead because it is out of their control.
