Sorry, I thought your onward was with China Airlines when you posted about it last year.
Its most annoying obviously if you get offloaded, but it does happen occasionally with all carriers except perhaps budget ones. On the positive side If your not in a hurry the points or cash or voucher compensation can come in handy. There is no excuse though for anyone laughing at you when you are faced with difficulties. You should be looked after properly.
Sorry you feel the way you do about the KL service. Perhaps you may one day try it again.
