I absolutely agree with the above.

Being the frustrated OP, I've tried everything you can think of ....

1. Trying English, Cantonese, Mandarin, and even Japanese ... no difference.

2. Trying not entering a MPC number, or entering an invalid one ... again, no difference.

3. (Very naughty) Using someone else's MPC number (a relative with DM) ... I was kindly asked to call again using my own MPC number.

The method that works best for me is to call around 1.55pm - 2.00 pm HK time, when lots of staff get back from lunch ... there's a sudden increase in llines available to be answered. It's worked each time last week (when I had to finalize my 8-sector around-the-world oneworld award ticket).

I realize that being a Green member I can't complain for being forced to wait. Being a Green member 5 years ago was okay - the MPC hotline was answered very quickly. It's just the last 2-3 years that's been disappointing.
