If the estimated delivery time has already passed, login 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 about the status of your delivery.
The Marketplace seller will normally respond to you within 48 hours of the incident being raised. If you do not get a response within this time frame, you may click on "Submit a request" below this article for further assistance.
