Amazon India — They're misguiding with showing lesser price and charging different price.

Address:

India

In today morning I saw amazon in shown Mi 11x pro price at 26999 and it had 5000 extra exchange offer, they shown this price will be for about 12 am night,
but
I had no money at that time and then I lend money from my friend and I came to place the order and amazon changed it's prices, they're still showing the same banner of 26999 price but they increased the price to 31999.
Kindly look into this, these shopping companies are misguiding people.
