In fairness, after the warning/scolding she went away to work on it, made the change and advised "only the $125 change fee" and I'll take a credit card when ready.

I asked her nicely to pull up the rules, directed to her about the date changes part...and she not only admitted she was wrong, but thanked me for explaining it to her. Quite refreshing in customer service these days to see someone willing to learn and admit their mistakes instead of digging in. My sense was she's seen so many of these with people arguing about massive price increases when making changes before departure that she wasn't willing to invest the time making changes if I wasn't warned ahead....
