| Baku to Los Angeles via Istanbul. I have not even taken this flight yet, it's coming up in March and I am already frustrated beyond words with the Feedback System. When my itinerary from Baku-LAX (17 hours in the air) was purchased, I bought seat selection for extra comfort, especially the long haul from IST-LAX and return. I had to make a slight change in the departure from Baku-IST by a few hours earlier. Because of this change on the initial segment of my flight, all seat selections for the entire itinerary were cancelled, a loss of over 200 euros. I chose to repurchase the seat selection again for a cost of 200 euro. After 2 formal requests to be refunded for the loss of 200 euros in cancelled seat selections, TK simply keeps referring me to the feedback form online and reminds me that I agreed to the changes before I confirmed that change in departure date. Had the vague message at the time of ticket change been made clear, something like "your seat selections for ALL seats on this entire itinerary will be lost" I would have never changed the departure date. However, the corporate response from TK continues to refer me to this feedback form which keeps sending me the same unsatisfactory response. TK prides itself on flying to more countries than any other, but who cares. The focus should be on improving the customer experience when dealing with people. TK staff have no decision making power and zero ability to change anything, even after talking to the "highest level" of customer service. Robotic staff who repeat the same corporate jargon and policies over and over are not trained at all to deal with real people with real issues. Get it right and start treating long term customers better or your once a week flights to random African destinations don't mean much.
