I am super warm all the time. I dont like flying Asian carriers TPAC because I find the cabin temp too warm.
I am usually very comfortable on AC, and would be very surprised if the cabin temp is ever 24C. I agree with 24Left in that it is usually probably closer to 21C.
You can always put on more clothes or get a blanket if you are cold.....Very difficult if it is too warm, especially if the air is stuffy -- ugh!
I don't EVER remember thinking 'Its too cold'- but have thought 'its too warm' many times.
It sounds like there was an issue during the OPs flight, but nobody wanted to admit it.
