Lenovo Mobile Service Center Vizag (Bright Infotech) — Worst customer service by lenovo

Address:

Visakhapatnam, Andhra Pradesh, 530007

I have lenovo k3 note, it's 5 months old. Starting 3 months the mobile was good, but later I faced issues with touch and battery. When I visited the service center they said it's software problem it will be rectified by NXT software update and on 25 th March I got a marshmallow update to my phone after updation the complaint was same, again I visited the service center they said there is official marshmallow update and as u updated it, there will be no warranty for your product.
I called the lenovo toll no. they talked with the service center and the person . He without even checking said it's not hardware issue it's software problem and return my phone.
