Lost Luggage on Air France

On Saturday 2 December 2023 I travelled from London Heathrow airport on flight number AF1281 via France to O R Tambo International Airport Johannesburg on Flight number AF0990. I checked in 2 suitcases, 1 big black one and 1 small black IT suitcase with white stripes on top at Heathrow airport. Upon arrival at Or Tambo airport, I waited for my luggage, and I received only the big suitcase. I waited for everything to come out and then a lady came to say that these were only the suitcases that had arrived. I told her my small black suitcase did not arrive and she asked for my name, and I told her then she told me that my small suitcase was not loaded hence it did not arrive. She asked me to go the Air France counter (if not mistaken it was counter 6 or 8) to register the missing suitcase. I went to the counter and spoke to Bongani, and he registered my suitcase on the computer then he gave me a note with Reference number: JNBAF56937. He said they would call me and deliver my suitcase as soon as it had been located. He asked me to call him if I did not get a call within 7 days. On the 14th of December 2023 I called Air France on the number that Bongani gave me ***and ***4 but the numbers could not get through. I called almost everyday until first week of February that is when I was answered by a lady called Beauty. I asked for Bongani or Tony and was told that they were receiving a flight from France. I kept on calling and being told the same story until I went on the Website, that is, when I saw that I could Claim for loss of my luggage after 21 days of it being not located. I logged a claim, but I did not receive an email confirming the Claim. I called again *** and a French lady answered, and she checked for me then she advised that the Claim was not registered I should try again. I tried more than 10 times but I could not get an email with the Claim reference number. Now I have been calling the Johannesburg office for someone to assist me to Log a Claim to no avail. The ladies who pick up the phone Beauty & Ntokozo said I can only be assisted by Bongani who is aways out of office receiving a flight from France. If Air France people are seeing this complaint, please assist me to Log my Claim. This has caused so much inconvenience as I had to replace all the things that I bought for my children because these were for school. Schools opened without their stuff. Your urgent response, will be greatly appreciated.
