Nissan Motors — Nissan qashqai unrepaired internal chest detachment

I bought a 1.2 petrol qashqai platinum vehicle in 1 year ago from kavuklar otomotive in izmir/turkey.
I noticed a detachment in the right anterior chest which was separated from the upper right corner. I took the car to nissan service to repair the the detachment. After repair, detachment was still continiung with little separation. Service man said that it is possible that this detachment might be due to the weight of the items that i put in the glovebox of the car (User's guide and music cds). Service man also said that we repaired this detachment as much as possible. There s still detachment. I sended 3-4 email nissan car company but they didn't reply my e mail.
