Turkish Airlines Didn't Let Me Board Because They Overbooked The Plane

I was going to take Turkish Airlines from Kars to Istanbul's new airport. In my hometown, the airport is very small, and the check-in process takes no more than 5 minutes. Even though I got there an hour early, they didn't take my luggage and said the system was closed and I couldn't get it. But I had exactly an hour, there was no line, and I later found out that they sold my ticket to someone else. Unfortunately, this happens more often in small cities. Because I didn't go in, they didn't take it even though I went extra early, I had exactly one hour, there was no density because it was the week after the holiday, I was victimized, I was victimized, I stayed in Kars, I lost my job, I was going to start work in the morning, they have no right to place their own people and victimize us, I ask that the right steps be taken, they did damage, they victimized me in every way.
