No response after send a e-mail to them

I bought 2 tickets online for Jurassic world (3D Imax) for 12 Jun at 20:15 in The Grove mall, when we get there, we were informed due to load shedding we can not watch the movie. The management from The Grove says they can not replace us in any other time, the only way is we need to go to the mall and check whether there are seats available for us or not. Due to the distance from my area to The Grove, it is not very convenient for us to go to the mall regularly. We were also informed if we request refund, we need to contact the head office of ster kinekor. After send the e-mail on 13 June, no one rep****, no one cared. Well done! Ster-Kinekor, now I'm not going to use your service anymore even it's IMAX, who cares
