Kind of a tough situation here. If you can't see any physical damage then you can't prove that they broke it. Also they can't prove that it was damaged by something coming in contact with it while you where driving.
Do you have any pictures? Where is the crack, on the side? On the flat bottom? I have seen people jack up engines by the oil pans with a block of wood or something between the pan and the jack to help get engine mounts in or a transmission out. Cast aluminum is delicate and could crack if too much stress is put on it.
