bad customer service

Visited ster kinekor centurion mall on 28 February 2015 to watch the 2:30pm show, 50 shades of grey. Standing in the line to book tickets and buy coke and popcorn since 1:45pm. Only to get to the front of the line at 2:40pm and the person serving tells me that they are only accepting cash, no cards accepted. So I asked him why couldn't they have put up a sign or have othere ster kinekor workers to advise that specific line that his card machine was not working, instead of having them walk around laughing and talking with all the women in the queue's. He told me its not his problem. He's sorry, he can't help me, I went to the manager, she took me to the specific cashier and then she said sorry they should have put up a sign and that I must go watch the next show as the 2:30pm show had started long ago. This kind of service is totally unacceptable especially considering I'm an avid movie goer and I have a vitaliity ster kinekor card. Was totally humiliated.
