Intercare not keeping to appointment schedule

I had a disappointing experience at Intercare. A private health care institution where customers pay good money, expecting good service. I had an appointment for 9:15, and as the receptionist asked, I was there at 8:45 to complete new patient forms. By 9:35 Dr. Booysen was a no-show. As I waited 20 minutes already without any indication how long I still had to wait (asked receptionist), and needed to get to work - I had to leave. So, my throat infection will have to wait. The pits will be if I end up getting billed for this!
