Passenger compensation

Passenger compensation not paid out in over 4 months after being delayed at frankfurt airport on 29 June 2025. My payment was not processed on the day due to system errors. I was at the airport till midnight waiting to be assisted but was told that I will receive an email requesting my bank details. I received the emails from Lufthansa customer care upon which I provided my banking details because they had informed me that the payment cannot be made to my credit card. Since July I have been following up without any response. I then received a response saying a payment had been made into a card with a certain card number. Luckily, when I was at Frankfurt I exchanged numbers with the other passenger who was also delayed. I contacted that passenger and she confirmed that the card number they are quoting is her card. I then asked for her banking details to send to Lufthansa to show the date of the transaction and also to show them that the credit card which they are referring to is not mine. I even copied the other passenger in my emails and she agreed for me to share her bank statement and copy her in emails to Lufthansa. To date I have not received any email or support. It is also difficult for me to phone Frankfurt as I am based in Johannesburg. On 3 occassions I have asked a friend in Germany to call Lufthansa and put me on speaker and I get the same message that I will receive an email requesting my account details. My colleagues in our head office in Germany also contacted Frankfurt airport and were told that due to the summer holidays in Germany there were delays in processing the compensations. Now its winter in Germany and noone has responsed to my compensation and they are insisting. This has been an extermely emotionally distressing period trying to get responses from Lufthansa
