Query: TERRIBLE PRODUCT FROM TERRIBLE SELLER

I tried to contact this seller about a broken/ damaged product. Not only did they not refund me, but the seller thought it unnecessary to write me back or even acknowledge my letter. So now i'm left with a crappy product from a crappy seller in an all-together crappy transaction on amazon's part. DO NOT BUY FROM THIS SELLER
