Sony India — Sony bravia klv 24p412b dead

I have a Sony led 24". The boy who came for installation of the Sony led broke the audio pin inside the Jack of the led. He destroyed my new led. When I complained about it then again the same boy came after 10 days being complained. He changed the Complete board. As soon as he left the led was dead. It means that he provided me a faulty part. Now the service center tells me that they need to take d led to the service center. First of all full day I am not free to repair the led. My led is not working is because of your fault. So I request you to exchange my led with a new Sony led. I cannot trust your service as well as parts wheather they are original and new. Contact me today and hopefully accept my request. One last question, Have I bought it to take free service or to use it?
