Jabong.com — unable to get my refund

I am unable to get my refund back from jabong. I placed an order in december and got it delivered in january (After 1 month). Then i wanted to return my product but my by that time i got my source account closed so i called customer care regarding same and they placed the return and advised me to mail them with return id and new bank details and i did the same.
But still, they refunded the amount to closed acct.
Now i neither have the product nor amount (Rs. 3013).

They are not ready to help either as they are saying that they have already refunded amount on the closed account and back is saying that no transaction took place as the account is already closed.
