Sir I got moto g5 s plus 64 GB  from amazon and used it the microphone doesn't work sometimes the voice is breaking in between while on call with someone ,and it's 15 days of purchase first I thought of network issues but all of whom I call complain me that your voice is breaking in between. What to do I want my phone replace as it's not properly working ,it's hard earned money and I prefer Motorola over others because I consider it as a genuine brand , how can I get replacement or my money back
