I have been using Amazon Seller for almost two years. At first, the list of items that I sent to the factories showed that every item I put in the box was received, so I stopped paying attention to the items that I sent. Slowly the items that I sent have started to go missing. But, I wasn't paying attention to it. Then for some reason, a customer order wasn't able to be sent so I went and looked, and boom a whole shipment of 38 items was received at the factory but all the items were missing. so far almost 2000 worth of items have been missing.
