HP India — Irresponsible behaviour

Hello, I purchased HP laptop 1 yr back during the whole year i faced several problems with the product which were rectified timely by the HP support. but when it was last day of the warranty the lan port got out of order. I couldnt make any complaint as the toll free services were closed at that time moreover HP online support was not working (since last fifteen days). Next day i called the toll free service the lady said it is out of warranty and hanged up the phone. she did not care to listen to the problem. I mailed to 10 people from where i got mail previously regarding the other issues. but not a single mail was delivered all failed indicating the email ids were fake. I again called the engineer he said he could not do anything on phone ahich clearly indicated that i have to pay now. I called the toll free service they said they have escalated it i will get call within 24- 48 h. Next day i got call (surprised) but the person shouted at me showing irresponsible behaviour. So what should i do now. Where to complain nobody is responding nicely.
