Need improvement
1. Take too much time (about 20 minutes to reach the CS) in waiting call pick up while call in the free toll hotline. 2. I did double checked the information I input on line for my tickets but don't know why name of ticket holder in the E tickets goes wrong (the last name being supersede the last word of the first name). 3. For user friendly, I would suggest to pump out a screen of input information which request customer to double check and save prior to move on payment.
