Don't you just hate them?

I booked a flight with Jetstar (Australian-owned budget airline company servicing the Asia-Pacific region) a few months back. In the days leading up to the flight, I had to change one of the names of the passengers, as one of our group was no longer coming and we roped someone else in in their place. I checked if there was a simple way to do this online (given, you know, it's the 21st century now), and there isn't. In fact it said that I had to call their call centre AND face a NZ$40 (US$32.50) charge. Overlooking the fact that this $40 was actually of greater value than the flight itself, I accepted it as the only way a budget airline makes money (they're also really particular about carry-on bag size/weight limits). So my friend-who-was-taking-my-other-friend's-ticket rang up the call centre and asked to change it. They told him that the person who made the booking had to call to change it. So I did. They told me that the person whose ticket it was had to call. So she called, but then she wasn't allowed to use my credit card, so the guy had to ring me, ask if she was allowed to use it, ring my friend back, and change the name/charge my credit card.

All three of us were told that the charge for a name change was $40. When the man asked if my friend was allowed to use my credit card, he told me it was for a $40 charge. The website says $40. So when I was charged $79, I was kinda bemused. I found this out at the airport, so I went to the Jetstar check-in counter to ask why'd I now been charged $79, which is more than the value of the actual plane tickets for all three of us travelling. The lady looked at me like I was stupid and said it wasn't her business, that I need to ring the call centre to ask why they did it. She may as well have told me to go ask at Air New Zealand why Jetstar had overcharged me, she was that dismissive.

I rang today to ask why, faced a 30 minute wait after a computer couldn't catch my Kiwi accent (it thought I was saying 'K' instead of 'six', until I pronounced it 'sex' like an Australian would), and was then told that the computer system is down so that they can't actually do anything. When I asked the man whether he could tell me why I had been overcharged in the first place he said he couldn't tell me (not that he didn't know).

Call centres are the Devil's handiwork. Please share a story.
