No banker allocated or updated

I have to do big transactions and need a business banker at all times, with my knowledge Joanne Lutchminarain was the allocated banker, on calling her today 08/02/2024 she said she’s no longer my banker and gave me details of another banker which are not valid or exist of a supposed Vuyanda Sibanyoni phone number doesn’t go through,

My complaint is I had not received any update that banker has changed and even the one it’s been changed to I can’t get a hold of, what u meant to do now, I’m being sent away at the branch to withdraw cash by rude consultants that say they can’t process my withdrawal for whatever reason, business is delayed because of all of this please resolve asap.
