Over charged

I gave a two star rating instead of one because when you submit feedback, the customer representives online respond very quickly. Also, the flights were decent and the air hostesses/hosts were very friendly and kind.

However, I had missed a connecting flight because I read the board wrong. That was fully my fault and when I ran to reach the boarding gate on time I got there two minutes later. I pleaded with the people checking everyone in but they couldn't do anything about it. I understand that but they were also very cold, started ignoring me and walked away just telling me I must find a help desk (the airport is huge). When i went to get a new flight, they charged me 480 euros (R9000) for the 10am flight . Just before then, my mom told me there was a flight at 10 which would only cost me R3000. They didn't allow me to get another ticket because they said they'd have the right to cancel my return flights with them. After speaking to people who work at airlines, they were very shocked because I ended up paying triple the price for that ticket. I understand it was my fault missing my flight, but it was my first time flying alone and I felt I was taken advantage of. I've been fighting for atleast half a refund on my ticket but I've just been met with the same response over and over again - that I missed my flight. That is not my point, my point is that the amount I was charged was exploitive. I wouldn't recommend flying with Turkish Airlines. My friends who fly with emirates had a completely different experience.
