poor workmanship

I purchased a brand new nv200 in nov2014 and requested sliding windows and smash and grab added. I specified that they must be nissan approved windows and even supp**** an email that warned dealers not to use other windows. Salesman confirmed it was a european standard. After 2 months of various excuses the windows were finally fitted in feb 2015.however they kept the vehicle for 3 days making various excuses for returning car. When it was returned the workmanship was shocking the body of vehicle was damaged and not repaired the smash and grab had bubbles and the left and right windows were different. Furthermore the doors had been resprayed and no one wants to inform me what happened. 3 weeks of fighting with nissan milnerton and nissan sa and tommie hamman agreed it was their fault and would cancel the offer to purchase and agreed to send paper work to attorneys. He informed nissan sa about this. At 1pm today he emails to say no documents will be sent since he wants a meeting with the RMI. This is unacceptable that a dealership can do as he pleases with no recourse from either nissansa or japan.with so many dissatisfied customers why has nissansa done anything .
