Nitro Circus JHB 28/10

I had purchased 4 tickets for the JHB Nitro Circus on 28/10 @ R 630.00 per ticket (R 2520) If that isn't enough already, a needed to purchase a parking ticket for the show as well - another R 280.00 So just to watch this show cost a total of (R 2800) and let not include petrol and so on. Unfortunately we weren't allowed into the venue because we were a bit late. I feel that this is truly unacceptable. We got stuck in traffic and wasn't able to make it at 20:30 I do not recall is saying anywhere that we will not be allowed entry after a certain time. I WANT MY MONEY BAC**** I paid a fortune for those tickets as a birthday present for my boyfriend and we didn't even get to see the show.
