Pandora Bay Selling fake Pandora jewelry Internet

Pandora Bay is claiming they are a certified online retailer of Pandora jewelry. The jewelry they are selling is not real Pandora. As soon as I found out they were fake I called my bank and reported them. My bank reversed the payment and blocked them from getting any money now and in the future. Pandora Bay sent the products anyway and are now harassing me for the money. I have repeatedly ask them for their address so that I can send them back but they are refusing to give it to me. They are continuing to harass and threaten me if I don't pay them. They can have their fake products back.
