Shocking booking system and worse service

I recently booked two tickets to Ster-Kinekor Cine Prestige at The Grove. I navigated to the Cine Prestige site online, selected the movie I wanted to watch and bought my tickets. When I got to The Grove we were told that our tickets were in fact not valid for the Cine Prestige. Upon contacting the manager we were told that this has happened more than once: the website will send the customer back to the normal cinema site, something that you must read in their 'Small Print' at the bottom of the page. In addition we were told that we should know where we book since the ticket price should indicate the correct cinema to us. The fact we had never booked for the Cine Prestige, and therefore would be unaware of the exact costs involved, appeared not to faze the manager. In addition, the fact that, on her own admission, this had happened to other customers before us also did not make her more inclined to accept responsibility and to solve this issue. Not only does the Ster-Kinekor website not do what it is supposed to, but their customer service was shocking and totally unacceptable. I had heard that the Cine Prestige experience is quite nice but considering their poor service and incredible lack of professionalism I am surprised they even get customers to their cinemas.
