Amazon India — Additional delivery charges after making payment

Address:

560035

Hi Team,

I recently made amazon purchase from my mobile application. While checked my cart and ensured delivery type is free then I proceed to payment. But after payment success from bank end, Amazon leaving me additional 50rs amount on delivery charges and it is providing me the option to cancel the order. The final page contains only one button "Place an order". Why the additional delivery cost not reflected in my cart, why there is no cancel order button at final order process page. is this kind of online selling strategy. I didn't expected this from Amazon. If it specified as Free in cart it should be free in complete order process. ORDER ID for your reference:
