Motorola Solutions — moto g turbo edition dual one sim lte black

Address:

Mumbai City, Maharashtra, 400067

I have purchased the handset of moto g turbo edition dual ne sim lte black in march 2017. Suddenly without any physical damage to the phone from my side, the phone switched off one day (This incident happened around one month back august 2017). After two days it switched on automatically. From that onwards when i call anybody my voice cannot be heard by the person on other side.

I gave my handset to repair in the authorised moto service centre twice located at borivali west, however apart from software update the people from service centre have done nothing to repair the handset and they deny any problem with it.

Requesting you to help me resolve this issue and how to take it ahead.
