We have an export customer who placed a telephone order for a shipment of goods they needed quickly. They gave us a purchase order number and instructed us to bill one of their subsidiaries.
We processed the order quickly and shipped with all the documents showing the customer as the subsidiary company as requested.
When we received a hard copy of the purchase order it was actually from the parent company and not the subsidiary. Now they are telling us that the parent company is the customer and that all paperwork should match the purchase order.
