FNB communication shuts down if problem is beyond service desk knowledge

I am looking for my credit card statements from 2021 linked to a different account fnb has given me. Been battling with the call center, their online App chat and have send mail .. no solution in sight for the past 3 working days interacting with numerous different people

I am of the opinion, if it was a straightforward request, it would have been solved on contact number 1. This has a kink to my problem, and the normal contact people do not have the ability to go beyond to provide customer service.

I asked for a manager contact.... still no response

There are no more channels to interact with FNB, if service desk (phone or app chat) cannot solve the problem, nothing can be further done. The last time I went to a branch they referred me to a phone to talk to service desk to find answers for the previous challenge I had.....
