Amazon India — Didn't Get My Refund

Address:	New Delhi, Delhi, 110082
Website:	amazon.in

I buy a phone from amazon and it came defected so i returned it. They pick my phone on 15spet in the morning and the maximum time for refund is 5working days. Now 7 working days are passes but i didn't get my refund. I called customer care they said order is still in transit it is not reached to the seller yet. In 7 days they don't send my phone back to haryana which is near to delhi. I want my refund back as soon as possible. I have to buy another phone. I am facing difficulties due to their poor service.I am also paying interst on emi which created due to the the transactions.
