Bad service = NO SERVICE at FNB

I left a review complaint on 19/7/2023. The bank rep**** to my review confirming that they are referring the matter to the relevant drpartment and they will call me. Up to this minute, I received NO calls or emails from FNB. I tried to make payment today and the bank sent an OTP TWICE but they sent it to the wrong number! I have updated my info during 2022. I am really gatvol for paying bank charges but I receive NO service. I need answers not later than 13 hours tomorrow, failing which I wi act as adviced by my attorneys.
