Yes. It is specified in Federal Law that a carrier must be paid in full for services rendered. If you withhold the carrier's payment partially or in full, they can legally hold the vehicle, until all applicable fees are paid.
Our recommendation in such rare cases is to first contact one of our experienced car shipping advisors via phone at {{phone-number}} or via {{live-chat}} and discuss the situation. In such cases, we are able to offer you a discount on a future shipment.
