FNB Consultant who doesn't know FNB Funeral premiums

I have a funeral policy with FNB.I called funeral call centre on 14 July 2025 and enquired how much premium would I pay if I add my younger brother.The consultant asked for my brothers date of birth.I provided her with the information.I asked for a quotation for R30000 and R50000 cover. She advised that for R30000 cover the premium is R75 and for R50000 cover the premium is R115.She advised that I can add him on the banking App. In the App I noticed that the premiums are different to what the consultant told me. The App shows R134 as premium for R30000 cover and R219 for R50000 cover. This is misleading and embarrassing for a consultant not to know premiums applicable to each cover amounts. I didn't get to hear the consultants name, she is a female.I want FNB to investigate this and I also want to cover my brother on the premiums I was advised by the consultant.
