bad service

My fianc? and I booked for the 14:00 show for fast 7 on the 11/04/15 at cresta shopping mall. We did not notice that the self service machine had booked the incorrect slot for us, when we went up to the ster kinekor staff they were completely uninterested but helped us reluctantly. They told us that they would give us a refund and that we should go back and wait in the 1m Que to rebook.. We found this absolutely ridiculous because the fault was not on our side it was on theirs but they absolutely refused to see our point. we did as we were instructed and by the time we got to the front, the movie was all booked out and we walked away extremely disappointed at the way the staff did not give a ****! we just found that this service was actually disgusting as the fault **** with ster kinekor!!!!!
