Unprofessional staff. Scheduled an appointment and was given a slot 3 weeks later. They confirmed it and then at the time of the appointment no one called or showed up. When I called to ask for a reschedule I was given another appointment 3.5 weeks later even though it was a scheduling mistake on their part. They then refused to be flexible with their schedule or make good on their mistake by offering me anything sooner.
