Lux Style International Sent me product I DID NOT order and an invoice to Pay. Odense C, Denmark Nationwide

 I was on the Internet when I got a pop-up for a consumer product "Quick max - eyelash growth enhancer", so I clicked on it to check out the product. When clicking on the product it asked for you to register your I information, and after seeing the price, which was very expensive, I left the sight. I received an email, a few days later saying my shipment was on its way. I did not recognize the email, and knew I had not ordered anything, and getting a lot of junk mail and other scams, I ignored it. Today, after about 3 weeks of the email, I received a package in the mail and before opening it, I had no idea whom it was from. So I opened the package and it had the eyelash product and an invoice for the product to tell me to pay within 14 days. I can only return it at my cost and have to send it with a tracking number to make sure it gets there and all this will be expensive to send it back overseas. It is disgusting that they can send product without my consent and make me pay for something I don't want and DIDNOT order.
