BROKEN CAR HANDLE

There was a couple of things that I needed replacing on my Hyundai Getz. I needed to have a new air filter replaced (it was taken out last year) as well as a light bulb to be replaced on the front cluster. I decided to send my car in for a minor service at the same time. On collection of the vehicle all that was done was the minor service. Nothing else had been done. I was told that they cleaned the air filter (There is not even one in the car to clean) and that the light bulb had to be ordered. As I drove away I noticed that my inside door handle was broken. I went back and spoke to the service manager Jan who told me that when he test drove the car the handle was broken. I said to him that is definitely was not broken when I dropped the car off that morning. He said that he would have to order a handle for me. To date I have not heard anything from this branch. Now I have to wind my window down and open it from the outside. Why must I pay for an expensive service and my car is worse for wear than before I dropped it off?
