Xiaomi India — Mi4i- Mic no sound in calling state

Address:

411015

I have Mi4i mobile handset from Xiaomi.
Recently I observed that, my mobile phone's mic is not working in calling state. The receiver is not able to hear me, if I have to put 'speaker on' then the receiver can hear me with lot of turbulence.

I had dropped my mobile to TVS Service Center Viman Nagar Pune on 6th Aug 2016 and they say will return my phone in 20-25 days.
Viman Nagar
I am calling to the service center landline phone[protected] from last 3 days but they had not picked my phone.

I was lucky enough, service center team picked up my phone today and they say your phone will take another 10 days for servicing & repairs.

Please note my phone is in warranty condition.
