So I reported both purchases as "problems," selected Other, and explained the situation.
Today I got an email from a support person re-stating what was said in the chat yesterday: new Macs less than 30 days old ONLY get free updates.
So I wrote back and said forget it, this is wasting too much time to be worth it. I clicked the links; I'm stuck with having paid for the software, and I'm unhappy. Apple, in at least one communication to the press, stated that these updates were free to all Mac owners who installed Mavericks. So I'm eating the cost. But because I'm an unhappy customer Apple won't see any more of my money for a period of one to three years.
Five minutes later I got an email from the same support person telling me that he was making an exception to Apple's "All Sales Final" policy and refunding the price of both updates.
Go figure.
What amazes me is this: Amazon figured this out with Kindle; when you buy a book you have a 14-day no-questions-asked return privilege. If you return it, the automated refund is almost instantaneous and the book magically disappears from yoru devices. If AMAZON can figure this stuff out, why the heck can't APPLE?????
Anyway, the updates showed up on at least one of my other Macs as being ready to download. So my problem is solved. But it did take perseverance.
And I echo Richard Olpin's comments...the program is radically changed, and not necessarily for the better. For example, there is no longer a Page Layout mode where each page is a separate entity which can be moved around to be reordered in the thumbnail view. Although the text areas of a document can be turned off, there's no obvious way to add pages or move them around.
The previous version was a great alternative to Adobe InDesign for most projects; the new version lost that capability. Sad.
