I had a flight at 8:30 in the evening. I boarded the plane at 11:00 at night. I missed my flight to Turkey because of the villager and you have to refund my money because I am the victim of this issue. And I slept at the airport until the morning and you did not help me in any way and I paid the flight fee and you have to refund my fee because I am the victim of this issue. I will have the necessary complaint lawyers with them because I was going to go to Istanbul on another plane and my plane ticket was burned and I could not go now. I landed in the Desert at 1:00 at night and my plane to Turkey took off at 12 at night. Such nonsense cannot happen. I am the victim but I am asking for your help in this issue. I paid about 3800 crowns.
