Spice Jet Airlines — Flight rescheduled

My flight was scheduled on 12th july 2022 from delhi to jharsuguda. I had some urgent business in jharsuguda but the flight was cancelled in the end moment and rescheduled to the next day. While booking if it is showing available and while payment as well it is showing available then how can spicejet cancel the flight. I donot have accomodation in delhi as well. Very disappointed.
