LuxStyle International Browsed their product - sent me a product with an invoice without having ordered it Internet

 I had seen an add on Facebook about a product called a peel off ask for blackheads. In order to see the price, you must enter your information (name, address). Once I saw the price and thought it was too expensive, I exited from the advertisement. A month and a half later, I receive 5 packages of the peel off mask with an invoice saying I must pay 29.85$ CND in 14 days. This is such a big scam. I have emailed them saying I am not obliged to return the product nor pay for it under ECC Finland ( European Consumer Centre in Finland) and they have threatened that they will keep sending me bills with late fees until I pay them off. This is not right whatsoever. They are not seeing any money from me.
