Somewhat disappointed with the service of the staff, the first time I came to redeem the voucher, I said it couldn't because there was no collaboration with Traveloka. Then I said it was impossible if there was no collaboration because here there was a promo on Traveloka but the staff still insisted on saying nothing. Finally I topped up the balance with cash. One week later I came again luckily it wasn't the staff yesterday. I want to redeem the voucher and I can. Next time for the staff, if there really is something like this, if you don't know, you should call the leader or superior for more details.
