I recently booked an mASA to Singapore. 60k points + $430 in business one-way. The agent I booked through straight away knew what I was after and was quickly able to help.
The problem came 2 days later when I noticed I got charged the $60 booking fee. So I called up to get the refund and this time I got an operator who had no clue with regards to the mASA I booked. At first she flat out told me nothing was removed from the website when it was upgraded at the end of June and I was wrong, the ASA was still available online. I tried explaining to her the changes for 5 minutes but she still didn't get it or believe me insisting she had "Been trained in the matter". I would normally hang up and spin the operator dice again at this point, but I was frustrated that she was saying I was wrong and if I hung up she would carry on being oblivious to the next poor customer like me.
It took 25mins of being on hold whilst she consulted some other department before she finally came back and had to eat some humble pie. She still didn't obviously get it though because she was saying how I'm better off booking a Classic fare because they're better value
I miss the days I could book it online...
