3 hours waiting and no movie

If I could give zero stars I would. Will never ever go back there in my entire life. Booked online to watch Avatar 2 at the IMAX at the Cape Town Waterfront, bought tickets online, get there and you they have "self service computers" to buy tickets which is the exact same as booking online basically, so even though you booked online, you still have to stand in the 1 and only line there is to get to redeem the tickets. This is also the same line where you buy popcorn etc which results a ridiculously long line because everyone is standing in the same line for different things. Also once you get to the front of this line they only then tell you they don't accept cash and that you cant place an order for anything without going back to a "self service computer" and ordinary and paying for it there and then coming back to "redeem" the voucher with your ticket. There are no signs anywhere informing customers of this. It's absolutely ridiculous. So after waiting about an hour for that and trying to go into the movie, there is another line and after waiting about an hour for that, we get told that apparently "due to loadshedding" the projector is fried and they don't have a spare one so the show is canceled and they'll give us tickets for another show on a different date. The fact that they don't have a backup projector is also absolutely ridiculous. We then had to stand in yet another line with the rest of the cinema to get a refund. The cinema still had the cheek not to apologize but to also take peoples half eaten popcorn and drinks back before giving them a refund. The very least they could have done was given them the rest of their snacks as an apology. Absolutely disgusting service. Wasted 3 hours of my life for absolutely no reason. Never seen such bad management in all my life. AVOID THIS CINEMA AT ALL COSTS, its an absolute joke.
