Amazon India — Totally Misguiding, Shown 26999 price for the day and changed it to 31999 within a few hours

I lend money from my friend to purchase Mi 11x pro, as amazon shown that it's available in 26999 MRP for the day ( they show timer also there)
and then I brought money from my friend and tried to check out and amazon increased price by 5000.
Amazon really making people fool by doing this, really very bad experience this time.

I want to purchase the device now, but they changed prices,
Even in the attached screenshot, the banner shows MI 11x pro price 26999 and after clicking that they show price 31999 (even in the morning the offer was on MRP and not including exchange offer)
