Turkish Airlines Lost Baggage Responsibility Issue

On 29.05.2024 at 06:55, I traveled on flight TK1821 from Istanbul to Paris, seated at 23B. Afterwards, I flew from Paris to Marseille with Air France. My baggage was not delivered in either Paris or Marseille. Despite all my efforts, I couldn't reach the Turkish Airlines lost baggage representative, Ms. Al**ia, at Marseille airport. She did not answer the phone at all. When I reached the Air France representative, they rightly said that the airline you handed the baggage to is responsible. So, I left the airport and filed a lost baggage claim online. Even after 3 days, no action was taken. Due to my profession as a seafarer and being on a ship, I could only call Turkish Airlines customer service today. They said Air France is responsible for my lost baggage. However, as seen on the attached baggage tag, I handed my baggage to Turkish Airlines and rightfully expect Turkish Airlines to resolve this issue. Air France also stated that they did not receive the baggage, shifting the responsibility back to Turkish Airlines. I urgently request you to inform me of my baggage's whereabouts and deliver it to my complaint address. If this is not done, I will demand the cost of the baggage mentioned in my complaint application, as well as the €320 shopping expenses I incurred in France due to this issue. Customer service says you are not responsible for the baggage you received, but you will be considered the worst airline in Europe with such irresponsibility. Irresponsible people... Moreover, there is no monetary compensation for forcing me to live with limited belongings for 4 months in the middle of the sea. If this issue is not resolved, I will take all necessary actions to track my baggage when I return to Turkey in 5 months. I don't even have a t-shirt, a shaving machine, or a nail clipper left, yet you do not take responsibility. This is sheer irresponsibility.
