Consumer Redressal

I have replaced my laptop hard disk and dvd r/w in September. They have given 90 day of warranty on product. Hard disk I started facing issue with Hard disk just before 90 days and eventually it got damage. After very deep analysis luckily I found that this hard disk was not a new on but old an repaired one and they did not removed the previous OS that is why I found that this is not a new one. It is very difficult to find this issue for an expert and this may be the possible reason for damage. I did not get any assistance until I drop a mail to their board of directors. Now no one is communication on mail and they are calling me and saying that it is entirely my fault that I did not bring this issue during the warranty period. I have also asked for information and declaration about the product that were new and not used one but did not get any response. I have already pain 10,000 to service center and new laptop will cost me around 40,000. Please help me.
