There seems to be an increase in inventory that is lost between FC transfers.

10 of my shipments received with discrepancies (shortages). And mostly these shipments were closed with "Investigation completed – shipment contents counted and confirmed" How is an investigation complete when the inventory ledger confirms they were received and then units removed in a completely different warehouse than we shipped them to?

I provided them invoices from the authorized supplier showing the correct numbers were purchased. I also provided them with proof of delivery as confirmed by UPS (correct weight with the units in the package), photo of the inventory. And screenshot of inventory ledger which shows clearly my shipments received in full at the first FC (TEBP) and after warehouse transfers my units were lost. However Seller Support Team is keeps replying me with pretty much same copy paste response every time that;

"I apologize for the inconvenience this may caused you so far and let you know that I did my better in order to assist you. Please know that when we receive shipments with quantity discrepancies, we automatically initiate an investigation on your behalf for the items in your shipment.

As part of this investigation, we perform a second, physical count to reconfirm the quantity of the items received. Items are marked “Investigation Completed – shipment contents counted and confirmed” when we have completed the investigation.

We have completed an additional check in response to your request. We have no record of receiving the units in question."

Thats very frustrating.I can see the same answers in this forum and hear from my other seller friend. as if the purpose of their reply is to get rid of the seller and answer the matter urgently.

Although we take the necessary care at every stage of our work, from preparing the parcels to sending them to Amazon warehouses, it is really sad to be passed over by the Seller Support Team due to the problems experienced in Amazon warehouses.

1- When i've provided them invoices, photo of inventory in the package and proof of delivery, what else they need from me to back up my claim?

2- Because they appear to have lost the inventory, it doesn't matter how many physical counts you do, it would bring the same result most likely.
