Xiaomi India — mic problem while calling

Address:

783331

I am satisfied with redmi note 4 but with one thing i'm getting annoyed. Whenever i call anybody or anybody call's me the person can't listen my voice. It is the most bad thing as we are getting more clear voice in lower prices as well i'm not talking about smartphone just a simple phone. So i request you to look at this case please that it is a bug or there is any problem in my handset. I will be very thankful to you.
