Lux Style International Sent Invoice for Unwanted Product Denmark Nationwide

I visited this website, LuxStyleInternational, which was on my Facebook News Feed. Before being able to view the finer details of the products, I was asked to enter my details such as my name and address. Upon entering this information, I saw how expensive the product was and exited the site.

A few weeks later, I received the product that I was viewing, even though I had not actually purchased this item with an invoice. Upon researching this company, it appeared that many people were also scammed by them and I was advised by many to not return the items or pay any money to this company.

I have since received further notices with penalty fees that were added onto the invoice. I, again, did not respond to these invoices. I have now received a letter that states my case has been handed over to attourneys for a court suit unless I pay within 5 days. 

I have looked at many articles online that have stated that this company is a scam and that the worst thing to do is to pay any money to them as many have done so and they have claimed that they have not received the payment.
