If container usage charges are inconsistent, freeze payment, shipment, or delivery for the affected vehicles rather than proceeding on verbal explanations. Put the vehicle, freight, tax, and local-service budget broken down by responsibility point in chronological order, then confirm which version is valid and who approved the change.
