HP India — display problem

I registered a complaint regarding my hp laptop with reference number [protected]. My laptop has adisplay problem and i gave it to the hp service centre. They told that my laptop's display ct number and product number is not matching. So they can't repair it. So i called in the toll free number and reported the problem. But they also told that the problem with my laptop can't be resolved. So i am forced to write this mail. I need a positive reply for this. I spend inr 40000 for buying this laptop. My laptop's warranty is not finished. So hp authority have the responsibility to repair my laptop. If i didn't get a positive reply for this. I am going to register a complaint in consumer court if i didnt get a positive report.
