Celtic Knot Jewelry review: Can't return no receipt

Purchased earrings (3 pair) online. Received the items and they were of poor quality and I wanted to return them. No correspondence with the company. They answered my e-mails with an automatic response and never got back to me. The items came with no receipt or return policy. When I was buying them my card was processed with out my clicking on a purchase bottom and the site Auto filled my information including the CVC three digit number on the back of my card. I never finalized this purchase Im out $240. I believe this is a fraudulent site,
