Query: Terrible Service

I bought this product some time ago, and the seller sent me the wrong product. So I emailed the seller and sent my product back. Now the seller stops responding to my emails. So I file a claim with Amazon. Amazon denies my claim. So here I am out roughly $30 and nothing to show for it.plain and simple I wouldn't risk purchasing from this seller
