Amazon India — Company shows the undeliverable product in their website and putting customer into trouble

I ordered a Laptop through Amazon using EMI option with CITI Bank Credit card and paid 32506.4 rs but Amazon did not delivered the product and refunded the amount 32506.4 rs back to my CITI Bank account. And as per Amazon the EMI should be auto closed in this case but CITI bank is not closing the EMI and asking me to pay 30000 rs extra to force close the EMI.
Amazon is directly saying that the amount has been refunded from our end and our job is done and for the EMI related issue Customer should run behind the Bank. But this issue has been created from Amazon side and they should help customer to close the EMI. If Amazon do not have the product then why they are showcasing those items in their website. I did not get the product then why should i pay emi or 30000 rs to close the emi.
