I've had a newbie leave me neutral f/b the same day she purchased saying 'item not received'. When I looked at her f/b left for others I saw that she had done this to a few other sellers - some had been left a green dot with the same comment and others had a neutral. With this buyer I'd just forward him the tracking number and sit tight - it's not necessarily going to develop into a 'not as described' case. Check out his f/b left for others - this will give you an idea of what kind of buyer you are dealing with. Don't stress over it - you are obviously doing the right thing and he will get his item - wait and see what happens. Good luck.
