Service not Provided during Warranty Period

I have purchased a Sony LED TV (KDL-32W600A) on 27.06.2014 from Siuri, West Bengal. TV has one year warranty. On 23.09.2014 this TV raised a problem of “Automatic Shutdown”. I have Informed authorised Sony Service Center at Durgapur (Contact no 0343-2587217) on that day. The Job Number of my problem/complaint is “J42246071”. One Mechanics came and checked the problem on 24.09.2014 and prescribed that one parts has a problem and will be replaced through service center soon. Till now Durgapur service center did not solved my problem. Whenever I call the service center they reply “Today Afternoon or Tomorrow Morning our mechanics will go and solve the Problem”. But the afternoon and morning never comes till now. During warranty period I am not getting my service as the Durgapur Service Center is continuously cheating me. I am unable to watch my TV after 3 months of purchase due to defective product and service of Sony.
