Nick, I totally agree with you and it is my point exactly - Nikon should take responsibility and take care of issues like that. In the end they will only win - I believe it is virtually proven now that the better the customer service the better a company does. I always am willing to spend more with a company that will treat me right and will rarely resort to saving some money on a service or product if I believe that paying relatively more will result in a better experience for me.
Thank you for sharing your experience. I'm glad to hear that you managed to get things right in the end. I don't think I'm at that point, but I am sure not happy with my experience so far. I was (and still am) willing to accept the faulty mechanism hoping for a fix, but if the fix is not possible, then I will continue and go all the way I can to get this issue resolved.
