Lenovo — Touch screen main buttons are not working

Address:	Chandigarh, Punjab, 160101
Website:	LENOVO MOBILE PHONE

I have purchase Lenovo k6 note before 3 months and it's touch screen main buttons are not working. The bottom 3 main buttons i.e. home, back and main buttons are not working at all. There is no service center in Chandigarh where I can reach as my phone is within warranty.

Rest all the other features of phone are working properly.

The bottom 3 main buttons i.e. home, back and main button's touch is not working. I restarted and rebooted it many times

I contacted customer care and everytime they are asking to restart the device but no resolution found.
