Hello,
The issue was not with FBA2GB8GDC specifically. The issue was that in Shipping Plan PLN3J962H you sent in FBA2GB8GDC and deleted FBA2GB8GCQ and FBA2GB8GC2. When Amazon begins receiving any shipment in a shipment plan, it expects that all associated shipments will be received to the correct fulfillment center within 7 days. To see your Shipping Plans, go to Inventory, Manage FBA Inventory and click on the shipping plan tab. Any shipping plan with a black triangle on the left has been approved. Click on the triangle to see what shipments are associated with that particular plan. If you prefer, I would be happy to set up a phone call with you so we can discuss in person and I can further clarify what we're looking for when it comes to deleted shipments. If interested, respond with the number you can be reached at and I'll send back some times that I am available to call.
Thank you for selling with Amazon,
