We're family of 6 (3 A+ 1 teen+1 x 9 and 1 x4) on Sin-HK-Sin flight. on our return, the HK ground staff (Eva Wong) was so rude and no customer service at all! The seats allocation are very inexperienced. We checked in 1 1/2 hour early and were told that we will seated separately - 1 pair at front aisle, 1 at the mid and 1 at almost last. When we request to have a nearer seat, the girl and i assume her supervisor simply answered that there's nothing can be done as we did not purchase the seats so we have to follow their allocation. I guess by choosing this BUDGET air yet did not choose to add their other cost we have to endure them, we pass it on take the seats and continue with the check in process. While she check in she told us that the 3 bags that we placed on the rail already meet the weigh and we cannot add further. My husband tried to ask the weight of the bag so that we can match our own, she was so opinionated and kept saying that already the maximun, very declining and not helpful at all. Frustrated we checked in, right after we turn our back, and turn back to take a glance, guess what?? This supposedly helpful, customer service orientated Tigerairways ground staff threw one our bag into the container with a very LOUD BANG! UNBELIEVABLE! My husband goes back to them and complaint to another staff assuming their manager and He(the manager) expressed that he did heard the BANG too!! He claimed he will interview the girl which we barely believe it would happen. He then offer to check in one of our bag free. When we reached Sin I tried to reach out to ground staff to file for written feedback - there's NONE!! Thanks to this specially trained lady staff my perfume bottle cap and eye shadow cosmetic cracked!
