EasyJet Flight from Kos to Milan Abruptly Cancelled

My flight from Kos to Milan with EasyJet was unexpectedly cancelled on August 28th, just 5 minutes before departure, leaving me without any explanation. EasyJet did not offer an explanation for the cancellation. We were given a document in Italian and instructed to submit a complaint. I was unable to finish my trip from Italy, and all the hotel bookings I had made went to waste, even the ones included in my return ticket. Even after sending them invoices, they declined to refund me for my flight tickets or the prepaid hotel expenses. Thanks to EasyJet, my one-week vacation was completely spoiled. I intend to explore all legal options at my disposal.
