Suing Fed-Ex

Does anyone know how to bring suit against Fed-Ex? While the human was out, they came creeping by in their little truck, and dropped off 200 backs for the books the human is planning to put together for herself and for the church. I tried to tell them that we weren't accepting the delivery of that package, but would you believe that they said as I wasn't the human it was mailed to, that I didn't have the right to tell them to take it back? The backs are sitting in the kitchen now, awaiting the arrival of the covers and coils to go with them, and then the assembly fun will start. Does anyone know how to make delivery truck repellent?
