Nu Metro - In it for the money, not the experience

Why are you ruining the movie-experience?? How can you treat customers so bad! I've made an online booking and we would like to either cancel or move the booking to a different cinema for another time (due to illness) but I can't seem to be able to do this! Your Nu Metro phone number either goes to voicemail or a lady tells me to send an email to your helpdesk!!! The helpdesk never replies! These are R700 movie tickets including snacks! So that's it then, money gone!! How can you run a business like this?????
