My car met with the minor accident on May 2013 due to which the driver side door was extremely damaged and the adjacent fender also had minor damage. The required repair was carried out in Automax Honda Mayapuri and the door was replaced.
Within 1.5 years I realised that the door and the paintjob undertaken on the door was so substandard that the paint has been chipped off and the door is been rusted to so low level that there are holes now( Picture attached). Made complain # 1-[protected]. The company made no follow up. They are still proud of there workmanship as they claim that i didnt report any issue within 6 months. How can a rust defect be made to notice within 6 months?
Other body parts of my car are absolutely fine, how can the part which is newer as compared to other body get rusted and not the other?

Then they said that we will repair the door for sake of goodwill, when i insisted that the door is beyond repair and is need to be replace and also offered that the difference between you repair cost and door i will bear, they countered offer that Honda will bear only 20% of the repair, which practically even much less than the cost of repair.
What kind of decision are they taking to fool us?

Another problem area is the AC of the Car, whenever you start the AC it keeps triping (almost every 20 sec) even when the temperature inside the car is not bearable. Have made complaint regarding the same in every service and in every service they change the thermostat setting. But the change doesnt really give the fruitfull result.
