I just got off the phone with Amazon.com after complaining about missing chapter links in the Table of Contents panel on one of my Kindle books. First I had tried a chat session, which took about 20 minutes and accomplished nothing. The guy gave me the runaround, asked me to deregister my Kindle for PC app and reregister it; then he asked me to remove that book from my device and then redownload it. Of course that didn't fix the problem. Then he wanted me to uninstall and reinstall the app. I refused until he could tell me he couldn't reproduce the problem at his end. He passed, and handed me off to a phone support person. That guy went through the same set of "diagnostics" which was a waste of time. I knew from the get-go it was a problem with the book, and all I was trying to do was inform them of that so they could fix it. Logos would have confirmed it was a problem at their end immediately. Yeah, they might have taken a while to get around to fixing the book, but they'd know I knew what I was talking about and wouldn't put me through humiliating noob steps. Ah, the benefits of having an active forum where the Logos employees recognize our names! And intelligent tech support people at Logos.
Thanks again Logos, for your responsiveness! It blows the competition away.
