Amazon India — discount added on a fake mrp

Address:	Mandi, Himachal Pradesh, 175001
Website:	www.amazon.in

I recently purchased a book from amazon, the mrp on the website was shown as rs. 602 and after discount i received it for rs. 397/- inclusive of all taxes and free delivery also. When i received the book the mrp mentioned on the back of it was rs. 399/-. On discussing this issue with they asked me to return the book and full refund of the same will be done. This is highly unethical on their part to display fake mrp on their site so customers will purchase the item thinking they are getting so much discount. They said i've paid less than the mrp so they have not charged me more than the mrp. I want the refund from them for the same discount on the actual mrp of the book. I also requested them to send me the chat but they haven't till now. My order id is #[protected]
