So, you sent the new item to Amazon for fulfillment and then Amazon shipped it. Is there a possibility that Amazon accidentally shipped the wrong item? Like maybe yours was sitting on a shelf next to an old one and they got mixed up. ???

I asked Amazon about this and they said they put each seller items in separate bins, so they can't get mixed up with items from other sellers. what exactly happens in their warehouse is hard to tell from outside.
