Turkish Airlines Call CenterCanceled My Child’s Ticket, Costly Rebooking

On July 13, my wife and daughter were scheduled to fly from I******* to B*****. However, due to an issue with my wife's travel, my 6-year-old daughter was to be accompanied by her grandfather. When I called THY customer service to request a name change on the ticket, I was informed that it was not possible, which I understood. Subsequently, I had a nearly one-hour phone conversation due to the following reasons, and as a result, my daughter's flight was still at risk. I believe the cause of this incredibly bad experience was the THY call center staff, and the amateurish handling of the situation and my calm responses to these amateur mistakes were very upsetting.

Issues I faced:
- When I asked how to cancel my wife's ticket and purchase a new one for my father since name changes were not allowed, the response was, 'How, how do we do it, whatever price you see online, you will buy a new one.' When I warned them about their tone, they softened.
- I was informed that I could cancel my wife's ticket and get a refund, but mistakenly both my daughter's and wife's tickets were canceled.
- My daughter's ticket should not have been canceled, and the lady at the call center said there was nothing she could do, that it was canceled by mistake, and that I could use the refund to buy a new ticket. However, the refund for the ticket that should not have been canceled would be partial, and buying the ticket now would be very expensive compared to when I originally purchased it. Despite my insistence, she only apologized and said there was nothing she could do, trying to justify her mistake. After my reaction, she said she would fix it, but this cost me a very long and stressful call.
- Since the ticket for my daughter's current flight was expensive, I wanted to organize both my daughter's and my father's flights for the next day, which was more affordable.
- The representative said they could help. They arranged a ticket for my daughter, I paid the ₺1500 difference, and then Bingo, oh, there was no seat left for my father, the flight was full, and he could be put on the standby list.
- Despite stating that my daughter was 6 years old and could not fly alone, I was told not to worry. They said my father was on the standby list and a seat would open up. When I asked what would happen if no seat opened up, I was told not to worry, that they would refund my daughter's money but with a deduction. This meant they both couldn't fly, the vacation plan would be ruined, and the refund would be with a deduction.
- I am not sure what kind of damage I will come out of this situation with, as I encountered someone who is far from professional, does not know how to use the system, and cannot manage the situation. I request that the call recordings be listened to.
