Fedex — Shipment not received and there is no help from FedEx

FEDEX AWB #[protected]
We are manufacturing traps for farmers in India and the time is critical. The shipment is received via priority from China on the 4th Nov 2022. There has been no update from FedEx except we have escalated the issue. The parts are stuck in the custom and this is not the first time we have imported these parts which are bulb holders. FedEx has been extremely cooperative by answering the calls and giving different complaint and tracking numbers but nothing concrete as to when the shipment will be delivered. Extreme losses are faced in multiple lacs by us and the farmers of which they have no concern at all. Email reply with specific times for a call back has been just to get the customers off their backs. I do not know if this is the FedEx way or just the India office which is extremely inefficient and unprofessional in their approach.
