Query: Return Shipping Issues with Amazon

The product was not as advertized. The original advertizing specified a steel roller. It arrived without 2 important pieces and could not be used. I followed the Amazon return process and sent the item back at a high shipping cost. When the seller was contacted they informed me that, contrary to the Amazon return process, I should not have returned the item. The seller refunded the sales price but I have not heard from Amazon. By providing bad return information Amazon has cost me return shipping. I have yet to determine my recourse against Amazon.
