Lux style international Harassment for payment of items I did not request. Scaremongering with threats of debt collection. Denmark. Internet

 I was interested in a product being advertised by this company. To obtain information about the product I was required to complete a form, entering my home address etc. Having done this I was taken to a page requesting payment. Acknowledging the extortionate price of the product, I decided not to proceed. I then recieved an email thanking me for my purchase!. I replied stating that I had Not consented to this order. I recieved an email back stating that luxstyle had already dispatched the item and should I not want it I would have to return it. I returned the item, via Royal mail at my expense and informed lifestyle of this. Lux style have since sent me in excess of 8 emails demanding payment for the returned item. I have consistently replied and provided them with proof of return postage. They continue to harass me and are now threatening me with debt collection.
