Website: Myntra

Myntra has delivered faulty bluetooth earphones last week. I had called trice to exchange or return the product and i am only getting false promises since then. As per policy i was supposed to get email for return or exchange within 72 hours and it's been week i have not received anything. Everytime i called they ask me to wait for more 24 hours and just fooling me with false promises
