I don't think that was necessarily due to your threat. I've noticed that often the first one or two or even three messages about an issue that I send to Amazon seem to be answered by bots (or people following a poor script) and they miss the point of my message completely, each time, no matter how clear and exact I am.* It's only after multiple messages that a real (free-thinking) human seems to actually read it and respond appropriately.

* I swear it seems like there's a simple algorithm that scans the message for trigger words and then chooses a response based solely on those trigger words. I've received responses to issues completely unrelated to my entire message, except for the fact that they're about something I briefly mentioned in an aside or something like that. It's horribly horribly frustrating, even when I know it's going to happen.
