I ordered tickets to Siam Park on the night before. Bank security check confirmed but the release of the tickets was delayed for a further security check. I was inconvenienced in sending mails and making calls to ensure that the security check was undertaken in time to print at hotel before leaving for the park opening. This with 10 minutes to spare. The additional security check came after the bank transaction was confirmed. There needs to be a cancel button to free the customer to take an alternative. Details of office opening times do not match reality. Calling at 8am got me a message to call back at 9:30. I can't see the online chat or the 0800 number either. The voicemail is out of date? I was attracted by "100% secure website...fast and easy booking". With 3m plus ticket sales it's time to go 365/24 instead of 365/office hours only...
