Spicejet - SpiceJet Flight SG 518 Repeated Delays and Inconvenience

I am filing a formal complaint against SpiceJet Airlines for flight SG *** (PNR S*GSWR) from Kolkata to Bangalore. The flight was originally scheduled for **:** AM but was repeatedly rescheduled with extremely short notice, first to *:** AM and then to *:** AM. This caused me to waste food and rush to the airport. After boarding, further delays ensued, including security re-entry and a shift to another flight. The plane finally departed at **:** AM, four hours late. This unacceptable series of delays caused significant stress, inconvenience, and financial loss. I demand an investigation, compensation for my wasted expenses, and a review of SpiceJet's rescheduling policies.
