A friend of mine dropped his lens and because he wanted it back with no dents whatsoever he waited close to three months to get it back because parts had to come from Japan all the while he kept checking his repair status to no avail. His also was conflicting. One day it would say one thing and the next another and then one day it was delivered even though the website said it was still in the shop. I have heard others complain about this. Nikon's service department needs to get together when it comes to updating their customers repair status.
I suspect that this must be a trend of the times, Once Nikon service and support of photographers was epic, but,,,, not anymore it seems, I stick with a local shop.
