Anyway, I tried to make a point in relation to the below comment, but my computer froze and I lost my post:

"... The best part is yet to come. I took my mother’s ticket and went to the QR help desk where quite a few agitated faces were waiting eagerly. But no signs of the “officer.” Finally, when he came, I raised my voice in frustration and asked him what the hell was happening. His response was in an equally if not louder voice, asking me to lower my voice first, which I refused to do until he explained why my mother was being denied a seat in the flight. His immediate reaction was to walk away from us and approach a police official sitting at one of the X-ray machines..."

Shouting aggressively at an airline official isn't going to achieve your desired outcome of getting your mother a seat on the flight. All you're going to achieve is to alienate the airline staff further.

Airline staff work under a lot of pressure and come in for a load of flack for problems that aren't necessarily their fault personally.

By shouting at them aggressively, you're not going to endear yourself to them, and they are not going to be inclined in any way whatsoever to go out of their way to help you out of your predicament.

You might achieve a more favourable outcome if you understand that their mission in life isn't to inconvenience you and your mother, they don't wake up every morning thinking: "Ooh, great, I'm really looking forward to annoying a whole bunch of passengers and getting shouted at today!"

If you treat them as human beings instead of verbal punch bags, you might find them more amenable and helpful.
