Unprofessional service

Worst and most unprofessional service I ever received. I had an appointment for 12:45 and when I got there it was super busy. No issue. I paid and took a seat waiting my turn. On the fly I heard the reception say dr is running late, no issue, I patiently keep waiting. An hour goes by and still no help. An hour and a half later, after all the patients have been helped I ask for the first time where he is and am told he'll help me shortly. Finally he comes out and says he has another appointment. Now I'm confused as I booked an appointment with him and paid. I asked him when he will see me, while trying to explain to him what has transpired, and he shrugged his shoulders at me, very annoyed telling me that it happens, I'll have to wait another 30 mins or longer. Shocked at his response I ask for my money back and the receptionist rolls her eyes at me amd asks me if I am serious. I was nothing but nice and to be treated in this manner is completely unprofessional. I expected more from a specialist but he obviously didn't need my money as he clearly didn't have the time to spare to honour his appointment.
