Amazon — iphone 6

I ordered an iphone 6 gold 32gb from amazon that was delivered to me on 20th september 2017. I've been facing so many issues with this phone in just two days time. Whenever i make calls the other person is almost inaudible. There is a problem with the earpiece. Also whenever i take videos or record audios on the phone the sound is as good as not there at all. Within two days i have faced so many issues god alone knows what's going to happen six months down the line. I ordered a phone from amazon because i assumed it's reliable. They provide the worst customer service and despite making multiple phone calls to their customer service executives i haven't been assisted with a solution to this. Previously i've ordered two phones from flip kart and i have never faced any such hassles. I wanted a decent phone and now i have to deal with all this unnecessary headache. I want a refund at the earliest.
