No support by FNB to provide confirmation of payment

I've been hitting a brick wall in trying to get POPs or confirmation of payment for the direct deposits made through FNB ATMs into FNB UJ tuition fees account. I've been in and out of Sunnypark branch following up on the documents and was eventually told by the consultant that the bank wont be able to provide these documents as "the transactions are old". The transactions were made between 2022 and 2024. I urgently need any written form of confirmation by the bank that payments were indeed made into the FNB account in question. These are required for a refund and audit purposes
