Catch doesn’t cover general returns for Marketplace orders. Most business sellers offer returns and details of their policies, as well as who's responsible for paying any return postage costs, are included within their listings.
To request a return of an item, go to your Catch account to contact the seller. Find the item in your “My Orders” and select, “Contact Seller”. From there you can raise an incident with the third party seller and request a refund or replacement product.
They will normally respond to you within 48 hours of the incident being raised. If you do not get a response from them within this time frame, you may click on "Submit a request" below this article for further assistance.
