Should physical therapy clinics notify and reschedule patients when therapists are out?

I confirmed my appointments for this week with my therapist Friday before I walked out. I didn’t get a confirmation text the night before like usual which was odd. I show up today and my therapist was out and I wasn’t booked for today. I asked if someone was available today or another day this week and she said they’re all booked. I got home called the office up and talked to the manager. Well they had open time slots with the therapist. I’m fumed.
