Trouble with Lufthansa's Lost Luggage Continues After 20 Days

On September 23, 2023, during my flight from Adana to Frankfurt with Lufthansa (PNR code: KSR8DF), and subsequently from Frankfurt to Canada, my luggage went missing, and they still have no idea of its whereabouts. It has been a painful 20 days, and I'm left without my clothes, important documents, and personal belongings that hold sentimental value. I've made numerous visits to the airport, only to be told to wait patiently. I've never experienced such a level of distress in my life. I'm at my wit's end, and I'm determined to initiate legal proceedings regarding this matter.
