FNB Agents not very helpful.

In March 2020, I changed my banking details with FNB in terms of my life and funeral policy because I am unemployed. They deducted the arrears on 1 April. In May they did not deducted and when I contacted them. They indicated that my banking details was never updated. When I asked how is this possible because they deducted in April. They further indicated that there was no funds available. I said that is not possible because all my other policies when off and I kept money for my policies with them. The banking agent cut the call. If my policy lapses I will hold FNB agents accountable. When the agents cannot deal with you they get an attitude and cut the call.
