Amazon India — amazon pay service

Website:

www.amazon.in

I recently bought a product using amazon pay wallet but returned it since it was a defective piece and the quality of the product was not as expected. Amazon returned the refund to my amazon pay balance and they dont provide a method to send it back to account and my money is blocked in the wallet and unable to use it. The customer care says that use it to buy another product and they cannot refund it back to the account from where i recharged the wallet. They are cheating indian customers. They provide this facility in us and why not in india? And their response was they need to follow rbi regulations. If so then how are other wallets able to refund the amount back to the account?
