Will Nissan North America help?

Dembflyr

Long story short, I picked up my car in Connecticut on April 2nd at about 2pm. I hopped in and drove about 50-60 miles away to a friends house. I live in Indiana and drove the car home the next day.
As soon as I got out of the car, I was looking back at it and noticed a chip on the rear fender (I will post the pic as soon as I can, using my iPhone to post)
I immediately snapped a pic and emailed the salesman. Well here we are 6 weeks later and after it goes up the chain I am told, that I must have done it because their detailer is the best and would have noticed it.
They told me that my $500- $600 estimates are too much.
The conversation did not end well with the manager basically calling me a liar and that I was "badgering them".

Does anyone have experience dealing with Nissan North America directly?

I am pissed and will take this as far as necessary.
