Voucher never came after paid, waited for a long time. Even until I arrived in Hongkong, standing in the front of the redemption counter. Still no voucher.
Chatted the help line from Traveloka. Told me to wait another 6 hours, 8 hours. Absolutely ridiculous. Decided to buy Octopus Card at the airport. way faster. Told traveloka to cancel. Had to wait for days for cancellation confirmation.
Please dont buy if you are in a hurry, maybe ok when you buy one week before.
