Shocking service

I have been trying to contact cinecentre for over a week now and have spent most of my monthly airtime in holding on and listening to all sorts of absolute *******. One call lasted 18 minutes and still, no call centre agent to take my call. I sent a "contact me back" request eventually after failing to speak to one single person and have yet to hear from anyone (that was Thursday last week - a whole week later). They charge an absolute fortune for a movie ticket (which one doesn't mind paying if you getting good service in return) and they cannot even have the decency to phone people back.
