Boat — i bought boat rockerz 510 from myntra, one side of the headphone is not working.

Website: Myntra

Hey, i have received my order yesterday from myntra. One side of the headphone is not working. So i reached myntra for exchange, they provided me a boat customer support contact.

I have called that number couples of times but my call has been disconnected each time. I have complained to every possible option available on their site. Please provide me

Hope you guys understand the scenario and do contact me asap and resolve the matter asap.
