Utter rubbish! Spent the last 30 minutes trying to book seats to Seinfeld in the PRESALE and apparently there were no seats available anywhere including both Sydney and Melbourne! I tested both just to be sure. The map showed plenty of zones with (apparently) available seats, which systematically disappeared as i frantically tried to book them. I wish this lot didn't have a monopoly on the industry, some competition might actually force them to put some effort in! Would give zero stars if possible!
