Amazon India — Movie ticket price

I have booked a ticket for KGF 2 for 15th April through amazon pay for Swati Cineplex (Dolby Atmos): Bhubaneshwar for 5.30AM show. the booking was done on9th April 2022. tghe booking ID -W9HWUFE. The ticket price for Diamond category of the particular theatre was Rs.300 . However when I was checking again the price on 12th April the price is now Rs.200. I think we have been charge more than the actual price. Change in price should take place after completing the particular show. Change in price everyday for the same show is against the ethics and rights of a citizen.
