Lenovo — Touch complaint- Lenovo K4 Note

Address:

695563

I had taken a new Lenovo K4 Note handset on 25th October 2016 from Trivandrum, Kerala, India. While I was using the phone I could not complete the process due to touch problem. When I consulted a service centre at Karamana Trivandrum they told that it would take 3-4 days to replace the same. The product is in warranty period.
There are more than 3500 contacts, notes, official messages and my personal camera footages in the handset. When I asked them to back up they told that it could not be done because new software tobe done after changing the touch. I repeatedly request them to back up the mobile memory. If the back up is not happen, it will affect my profession.
Kindly do the needful. If I loss the datas I have to propagate against your company in social media also.
