For safety reasons we are unable to allow order cancellations. Once an order is placed, our automated system immediately dispatches your order and it may already be on a delivery vehicle on its way to your home or business. Consequently we are unable to cancel your order and avoid the risk that a delivery will not be attempted. In the event that your tank has been filled by another company, and our dealer attempts a delivery, it could result in an accidental oil spill or release on your property. If you have accidentally placed a duplicate order, please contact us ASAP at firstname.lastname@example.org.
