Lenovo — lenovo mobile voice not heard on other end

Address:

Ranchi, Jharkhand, 834008

I bought lenovo k6 note on 8 june 2017. The mobile was not working properly as during a call the other end was not able to hear my voice. I asked for a replacement on 29th june 2017 in ranchi service centre (Sai tower). I was told that i have to submit it for service which i did. After a long period of around a month i was given my mobile on 29th of july 2017 (Saturday). The first call was ok so i returned home only to find out that the problem was the same.. It was really frustating after 1 month i was returned the mobile without proper functioning. So on monday i returned to the service centre after much debate the manager (Randhir kumar verma) asked me to submit my mobile again i conceded and asked to submit my mobile this time i was told to wait as they said the login in jamshedpur (Where my mobile was sent as they said) was not closed, despite waiting for two hours no positive response i have returned home feeling cheated. That my mobile is not repaired even after such patient wait of 1 month (My mobile is just 20 days old). I wonder what to do with this faulty handset. Thanks a ton lenovo in all the wrong way... All my money and time wasted... Now i end up with this faulty handset.
