Flipkart cancelled my order on their own

My order just got cancelled before the day of delivery, which was delayed by 2 days. At first they showed that my order is being shipped and will be delivered on 16th October 2023, but then they showed that there was a delay or two days and will be delivered on 18th. On 17th I checked Flipkart app, it was written that my order is cancelled! I placed my order at the time of sale (3000/-) and now the prices will never get same. Atleast they should have given me the option to place another order on the same price.
