I personally ship each of my units to Amazon. I have a particular product that comes in cases of 6 and I sent 4 cases to Amazon for a total of 24 units. Amazon confirmed receipt of the 4 boxes but stated that I had just submitted 12 units and closed the shipment. They also said that I had "Inaccurate item quantity in box" for 2 of the boxes which was the missing units. Even though UPS weighed those boxes and said they weighed 9 pounds each and Amazon received 4 boxes, they are saying that they were empty.

So I not only took a very serious financial hit (these are very expensive items) but now Amazon is saying that I'm above the acceptable problem rate.

I couldn't open an investigation because the case was closed so I opened a case through seller support. I talked to them and provided the required documentation (invoices, shipment confirmation) and they said:

"Thank you for your patience while we review your shipment 12345. I know that this is important to your business.

When we receive shipments with quantity discrepancies, we automatically initiate a review on your behalf for the items.

As part of this review, 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 review.

We have completed an additional check in response to your request. We have no record of receiving the following expected items:

12345 / -12 Units.

For more information, go to "Reconcile your shipment": "

So now what? I'm still relatively new on Amazon and not sure what to do. I physically packed each unit and weighed them so there's no way they weren't received. I read on forums that when you use manufacturer barcode (which I did) that it can lead to more lost units. I won't make that mistake again, but what am I supposed to do?? I can't just move on. I need these units to be found.
