Amazon India — not taking back mobile phone given twice due to technical glitch

I ordered a mobile phone from amazon india and the amount was deducted from my account then i received an email about declined payment and to revise the payment i clicked on the revise payment link and payed through net banking. The other day i received two same mobile phones and amount deducted from both the payments. I called the customer care several times and they haven't taken any action against this.
