Private Banker Luyanda Dikiza of no use at all

I have been with FNB for many years and with the account I have I have a "dedicated" private banker. Through out the years there has never been one that I could say was in anyway useful. I now currently have queries, I have sent emails to her 'assistant' with no response I had to contact FNB to get them to get my banker to call me, who when she did had such an attitude. I refuse to be treated like this, and I told her this and requested that she gets a person who knows how to treat a paying customer. Because she doesn't. Her name is Luyanda Dikiza
