"Always running late"

My father has been attending at his appointment, being told to be there every day for 4 weeks 30 mins before his treatment. Every day he has been seen late bar one day. No explanations, no notifications given whatsoever from the staff. We are travelling at busy periods every day, earlier than needed to ensure we get there before the appointment. It's extremely disappointing and wouldn't be acceptable anywhere else. At least notifying patients would be a start.
