Sony India — Breakdown of Sony VAIO laptop frequently

My Sony VAIO laptop's performance is really poor. I purchase it before 1 & 1/2 yrs. After my warrenty period I repire it before 3 months. Now my laptop is disturbing once again. It showing error & restarting it repeatedly. It also blinking. I am really frustrated with my product. For servicing I visit ur authorised service centre in Midnapur. But they suggested me to format it at my own risk. They also told me try to repire it yourself. I was ashtonised with their answer. Now I am feeling really sad with your product because I unable to complete my work. Now my question to you, who is the responsible for my financial & emotional loss? Please take my complaints seriously as quickly as possible.
