Cannot provide proof of payment for 104 transactions

I logged a ***** case where 104 payment transactions were made to approximately 11 bank accounts over a period of 14 months. The FNB ***** case number is ***. The problem here is they want me to provide proof of payment for each transaction. This is information that resides within their banking app. Some transactions were done as early as 16 Jan 2025. I don't even have access to that data. But FNB staff can access that data. So I believe that asking me for data that I can't access is simply ridiculous !!
