First off, call Nikon and tell them of your intent to contact the AG first. In my experience with a retailer, that evoked prompt action without even actually having to call the AG. Nikon is an outstanding company, but we all have our bad days and make mistakes. Let them know you are genuinely miffed. Tell them you don't know what else to do because you know your lenses don't have issues, since they work fine on other bodies. Tell them you deserve a replacement body. See how they react first.
