Lenovo — Lenovo phab 16gb screen is not working

Address:

Munger, Bihar, 721301

Hi,
I bought a lenovo phab from flipkart on 17 january 2017. After using it for 5 months, the dolby was not working. Then suddeny the touch screen was not responding at all. I reached toservice centre in behala, they told me that it requires 10 to 15 days for servicing. The other accecories in the box including the headphone and charger was not working. After 8 days, i got a message from service centre stating that "your handset condition will be not repairable please collect your device with jobsheet at lenovo service centre". The device was used correctly. No external damage had been caused. I want an replacement for this device.
