IndiGo Airlines Website Error Led to Costly Last-Minute Ticket Purchase

I purchased a ticket from IndiGo Airlines to travel to Indonesia for a flight scheduled at 8:00 PM on January 15, paying approximately $620. At 4:22 PM, when I attempted to complete online check-in through IndiGo’s website, the system repeatedly returned an error and displayed a message stating that I needed to contact the airline regarding my ticket. I had traveled from Antalya to Istanbul, and when I arrived at the airport, I saw that the IndiGo office had already closed at 6:55 PM. I was unable to reach any authorized representative, even though my flight was at 8:00 PM. When I asked the airport information desk, I was told that Skyjet handled IndiGo matters, so I was directed there; however, they stated that they only sold tickets and were not responsible for resolving this issue. Since I could not resolve the problem either through the website or at the airport office, I was forced to purchase a new airline ticket from another carrier for approximately $1,380 in order to travel to Indonesia. In addition, I had to cover extra expenses such as accommodation and taxi costs. Because the online check-in system was not functioning, the airline office at the airport was closed despite the flight time, and I was unable to reach any responsible representative, I believe that all of this hardship is entirely the responsibility of IndiGo Airlines. For this reason, I am requesting full reimbursement of the approximately $1,380 I was forced to pay for the replacement airline ticket.
