Poor and unprofessional service

I took my Nissan Datsun Go to the dealership on the 1st Nov 2017 as it had issued which failed to be resolved in the earlier years. The car door panels had sounds as though they were lose and the colour is fading as if its an old car. Today when i went to nissan to collect the car the told me that the mirror clips were broken as the took out the door panels. They said that paint is fading because of the sun. The manager was very rude and told me that there is nothing he will do the car is out of warranty
