Greed for money ruined my birthday

This restaurant made it their mission to ruin my birthday celebration. I phoned 2 weeks in advance to book my 21st. The manager was so greedy for money that he failed to mention the age restriction of 23 after 6pm. He took my reservation for 30 people for 5pm with a deposit of R2000 for food and drinks. Upon my arrival with my guests I had come to find other customers sitting in the area that I reserved(my guest had to stand). I had to deal with the rudest most inconsiderate waiter on this planet who did not care about anything and asked us all to leave by 7:30pm because of our ages. It was then when I got angry and demanded to speak to the manager that arranged my entire party but the man did not show up for work that day. I asked for my deposit back and the waiter refused to give it back saying we can stay under the conditions that we stay hidden in a corner in case the metro police show up.(How do you hide 30 people?) Anyways we ended up leaving because every time I tried to solve one issue another one popped up and it didn’t help that the man who took my money ran with it. Thank you Newscafe for Ruining my night with your greed and poor customer service.
