My product worth $38000 was lost in FBA warehouse, but Amazon refuses to pay.

2 different shipments I sent to FBA warehouse were lost,

Amazon initially said that these packages had been received and were in the process of distribution,

They did not respond to cases for months,

Now they claim that they did not receive the units. I sent the POD document, the carrier proved that they delivered the package, and sent me the POD document, and Amazon initially said it received the package, but now denies it.

Shipment ID: FBA15GPBWP2C

Case ID: 9787403562

I also sent the POD document and purchase invoices, but they refuse to pay,

Also, they have not responded to the cases I created for the other shipment for months.

Shipment ID: FBA15GFG8D87

Case ID: 9460537602 (They have not responded for 6 months)

9787393262

9861757382

This package was sent almost 1.5 years ago, and I created a case for this shipment many times. However, they never pay attention to me and do not respond to cases.

Amazon keeps losing boxes and never pays for them.

I believe they received these units and sold them to customers secretly from me.

Please help me.
