Amazon India — samsung s9 purchased in the big billion day sale

Address:

Bangalore, Karnataka, 560044

I purchased samsung s9 by exchanging my samsung s7 edge mobile. Within 3 days the handset stopped working. Whenever i dialed any number, the message would be "phone not registered". If some one called me on my number, the message would be "phone switched off". We contacted customer care today. After making all exercises for 20-30 minutes, they said phone is not working and would refund the money. I am not interested in refund, i need replacement. If refund, then they should return my old s7 edge. They expressed their inability to give replacement as they do not have stock nor return my old phone. This is unacceptable to me as i have not sold my s7 handset but only exchanged for new s9. If you deliver defective instrument, it is your duty to replace it.in whole of this bargain, i have sold my s7 edge handset tp you instead of buying s9 from you.
You need to resolve it immediately as i cannot stay without mobile as well.
