I talked with folks at this number as well.. they are just $8/hr ppl working a call center... they are sub-contracted by nissan and their primary purpose is to screen in bound calls/inquiries, not resolve issues.
Nissan reads this board... this is the place to get your voice heard.
In addition, re-posting coordinates if you want to write them.
