Lux Style International SENT ME 2 ITEMS THAT I DID NOT ORDER REQUEST PAYMENT IMMEDIATELY DENMARK Internet

In the mail I received 2 items fo Quick Max eyelash growth that I did not order. I was surfing the net and this item popped up while I was looking. I did go in to see what it was all about. I did not place an order for this product and was surprised when the item turned up in the post. There was an invoice stating that I owed them $64.85. I didn't think much about it and wandered how they got my address. I received a second invoioce with a total of $74.85 with another $10 included for late penalty fee. If I do not pay within 10 days they submit the right to claim directly to their local law firm that they use as their partner, with associated additional costs. I would accept full resposibility if I placed an order for this product and gladly pay for it BUT I DID NOT. How can I be resposible for the invoice when I did not place the order. Hope you can help me as this is casusing me undue stress.

Many thanks
