     Please listen carefully to the following information..."

Handling Responses:

Confirm: "Great! You're all set for Thursday at 2 PM.
        We'll send a reminder text the day before."

Reschedule: "No problem. I can help you reschedule.
            What day works better for you?"

        from your calendar, or would you like to
        reschedule for a later date?"
