[Resolved]  Flipkart — lenovo k6 power mic problem

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I have purchased lenovo k6 power in mid of aug2017. From then onwards there is issue in mic of my phone but i inquired they told me it will be resolved in there latest updates of lenovo. Recently i visted lenovo care center they changed some parts of my mobile (Initially they changed my ram from 4gb to 3gb) after telling them it is a 4gb phone, they searched something and change my ram. After this mic problem deteriorates and it is not possible for other person to hear my voice clearly.
I felt cheated because if at the first place my phone is replace by the good working phone then i don't have to face these issues.
Again if i try to go service center then also i don't know what they replace and why (Or might cause any other problem)
