Amazon India — Delivered defective item and closed my account.

Address:	New Delhi, Delhi, 110018
Website:	www.amazon.in

I ordered a Gionee F103(Black) from amazon.in for about Rs.10000 which got delivered on or around 25th november. I received a defective item and that too not on time as promised by amazon. I was in discussion with amazon.in about my refund, where they were totally rude and suddenly they closed my account and now i am left with the defective product and amazon.in is not answering to my emails nor they are providing any support over the customer care. Neither they are returning the product nor they are providing any refund. Immediate help will be highly appreciable.
