Luxstyle international Quickmax (luxstyle international) They invoiced me for a product that I did not buy! Odense

 I saw an advert on instagram and clicked on then I browse the page to understand what was it then I understood it was a lsh serum but before I entered my address detail and email adress as I thought it was to register for some kind of gift because it wasn't stated that I was buying something. Then on the next page it said pay with paypal with the price information of the product as soon as I saw that I closed the page without entering any payment detail nor accepting to buy anything. However I then received a shipment information email, I emailed them straight back saying that I didn't buy anything so do not send any item. But ignored me and said that if I filled in my address info it meant that I bought the product and they said They can't cancel because it is already shipped but I could send it back once I received it. Also they ask me to pay the postage fees.
