Skoda India — After serving

Yesterday I gave my car for service, and today I received the car after serving, I found the problem in front door glass besides driver side which was okay before serving and I found malfunctioning who is responsible for that?. After serving of car your company person is not checking properly all functions of car and the costomer has to suffer a lot. One person from your company came to my place for solving the problem but he couldn't solve the problem and told me that I have to take this car in the workshop and the workshop is about 15 kilometres away from my place so the petrol which will burn is of whom? Inconvenience caused to me who will pay for that. It's your negligence and you have to bear all these. Very bad experience.
