Any orders made through Noom's platform are not viewable by our team. You will have to reach out to their customer success team for assistance. Noom should have also sent you an email receipt. The email's subject line should read, "Your Trifecta Meal Plan Receipt" and it should have been sent from the email address, 'updates@message.noom.com'. In that email, there's a paragraph that explains how you can cancel from your Noom app or Noom portal page. You may also visit the FAQ on Nooms website which shows how to cancel.
