Does anyone know how to escalate a case of an AGL shipment not showing up on AWD Inventory after four weeks?

AGL-AWD Seller Support have not been able to give us any update.

The AGL Proof of Delivery shows

• Arrival date: 2024/10/09
• FC scheduled processing end date: 2024/10/13
• Unload date: 2024/10/21

Shipment references

• AGL Shipment ID:STAR-QJTFXFNN5PE2M
• Amazon reference ID:2RA7HSHZ

Amazon Case ID

• Case ID 16556285401

Any help is much appreciated

Thanks

Mark
