POOR SERVICE FROM FNB

I have a policy with momentum of which FNB is the cessionary bank. In order for my policy to pay out I require a simple cancellation of cession letter from FNB. I have now been waiting for this letter since the 16th July 2024. I have made countless visits to the branch in George and the only feedback I get is that "there is no time limit" in which I can expect this letter to be sent to Momentum. Further more no one there is able to assist besides sending emails repeatedly to the relevant department of FNB. This is ridiculous and shows NO effort from FNB. Further more I see that someone else has complained about this exact same issue with FNB on this platform. It seems impossible to make any progress thanks to FNB simply neglecting to do what is required of them.
