Lenovo — display not working

Address:

Ernakulam, Kerala

Sir,
I am a working professional. For my higher studies I purchased a Lenovo B 40-80 laptop 2 years ago. After six months it showed keypad complaints. Its back space key, delete key, caps lock key and volume adjusting keys was not working properly. But now its display is not working. So do the needful.
I bought this laptop for 30, 000 rupees and I did not get any accessories the only thing I got at the time of purchase was laptop carry bag. So i request to provide me with necessary accessories and resolve my complaint as early as possible.
