2. Dispute it with your bank (Section 75 or Chargeback)
If you are returning the rug simply because you changed your mind, their terms and conditions technically state that you must pay for returns. However, you have strong grounds to argue that their website is deceptive. By using a .co.uk domain, a UK freephone number (0808), and advertising "Free UK Delivery," they actively lead customers to believe they are buying from a UK-based business.
If the company refuses to help, contact your bank:Section 75: If you paid by credit card and the rug cost between £100 and £30,000, your credit card provider is jointly liable. You can open a dispute stating you were misled by the retailer's geographical location and hidden return costs.Chargeback: If you paid by debit card, you can ask your bank to initiate a Chargeback for the same reasons. 3. Negotiate a partial refund (and keep the rug)
Retailers know that international returns are a massive hassle and cost them administrative time. If you email their customer service and complain strongly that their Swiss return address was hidden behind a UK storefront, ask if they will offer a partial refund (often 30% to 50%) to settle the matter while you keep the rug.
