Something similar happened to me. The delivery company returned two packages, two separate orders, as damaged back to Amazon. They were marked as "delivered". They automatically refunded just one item in one of the returned orders.

I had to call them to get a refund for all the items on all the orders, and even then they had a lot of difficulty figuring out what was happening. Isn't Amazon supposed to be a world leader (maybe after Walmart) in this stuff?
