It's easy in the app, the portal, or by text. Any scheduled appointments will appear on your dashboard after you sign in to the app, or on the My Appointments page of the website. From there you can select Change or Cancel to change your appointment time. On the day of your appointment, you'll also see status updates about your technician's location. You'll receive text reminders the day before and the day of; you can reply to the text to change your appointment time without calling or signing in.
