Sorry to hear that you have had a problem with your purchase.
In your particular case, you made your purchase through the Amazon Marketplace, not our retail website.
The terms and conditions of our agreement with Amazon require that you process your return or exchange through their customer service portal using your product order # as identification.
Please take a few minutes to access your account, go to your order history, click on the order and request your exchange through this mechanism. We will respond quickly and efficiently once we receive that information from Amazon.
