I agree with you. This also happen to me and my family just a few minutes ago. We are having a trip to an island and had already booked the tickets online but did not print the voucher even if there was a clear instruction to print because I thought maybe we can just persuade the terminal attendant. Unfortunately, the attendant could not assist us because they could not retrieve our bookings. They needed the printer voucher.
We've struggled several options to have the voucher printed, unfortunately we were not able to print it. We have no other choice since we are running out of time, but too book/buy another set of tickets.
A good lesson to learn.
That sucks that you had to buy another tickets. I am surprised that it was no way for them to retrieve your bookings. Maybe they made it like this on purpose to make more money on cases like this. I would not be surprised.
Maybe and I would also consider their reason that they don't a internet connection yet to retrieve my booking. Granting that, they have a very poor customer service. Why would they start to serve if they dont have a net when most of their bookings are done online. Not a good alibi at all. Very poor review for them.
