I think I have an appointment for somebody to clean our filters, but I'm not sure when that is. Can I do the same time on Wednesday next week? That'd be great!
Oh, we can help you with that. The schedule is for today between 3 to 6 PM. Someone is trying to call you to move the appointment to 7 PM because our plumber is currently stuck at a previous appointment. Or you can reschedule it entirely if you're not ready.
