Movies@ Silverstar

I made an online booking. For unforeseen reasons I need to cancel my booking. I phoned your onsite ticket counter and got a very rude "Hello" As I was explaining my story i got told to wait and she was speaking in her language to another person. He asked if he can assist and I explained again, being advised to please come in to Silverstar so they can cancel the booking. I don't mind following a process to get this done, but being rude for no reason is unacceptable and unprofessional. Phoning the number provided for queries is just ringing and not answered at all. Why have this options if nobody can assist? If this is the service you get from Movies@ Silverstar, I'd rather go to Cradlestone.
