Motorola Mobility — Moto M mic stopped working after latest update.

The mic for my moto m stopped working after patch update 5 may 2017. I updated my phone around 28 june 2017 after which my mic used to stop working after making a voice call over apps like whatsapp etc. I had to restart my phone each time to make the mic work for phone calls. It would work fine for whatsapp calls. This makes it evident there was a bug in the update. After that on 3rd july 2017 I updated my phone to another update( nougat 7.0) provided by moto. This time hoping that mic issue would be fixed. But now the mic would work fine for apps like whatsapp etc. But won't work for the phone calls. Even the restart won't fix the issue. With the latest update motorola defeated the basic purpose of a phone. I can't receive or make phone calls as the other person can't hear my voice. I'd want the serious action taken against lenovo. For providing updates with serious bugs and moreover not providing a fix for the problem. This is a very serious issue as i cant make and receive phone calls and lenovo alone is responsible for that.
