Disappointed in Ster-kinekor

I bought The Lion King movie tickets online for me and my son playing at Cedar Square today at 5:30. The system accepted my payment but didn't send me my voucher. As if that's enough, I get there and explain my story only to find my seats sold to other people. The manager then sent me to Fourways mall to watch there, he promised to contact the cinema before I get there and also give me a call. As if that was enough, I got there and the movie was sold out and he never called me. On top of that, I paid for 3D and he sent me to go watch 2D. I haven't heard from that guy even now and I didn't even get to watch the movie
