Keep in mind that you can cancel a single order but still maintain a recurring schedule following the cancellation, see "Skip this service" below.
Cancelling an Order
You can cancel an existing order by going to the "Accounts" tab and clicking on the "Cancel service" button.
Skip this Service
If you set up a recurring service and only want to cancel the next order, you can click on the "Skip this service" button. This will only cancel your current order but leave you on the schedule for your next one.
