Poor service from FNB Private Wealth

I've been banking with FNB for 13 years and currently a private wealth client. My banker, Mohammed Khan called me a year ago to set up an appointment but didn't pitch. He didn't even bother to apologize. I just left it, however whenever i needed any assistance went through the private wealth suite and struggled to get good service. Up until now, they couldn't answer my ebucks questions. They asked me to call ebucks direct which I did and ebucks referred me back to my banker. Really pathetic service. I've requested a dowgrade a week ago and they still can't facilitate. I'm really disappointed at the poor service received especially being a private wealth client.... Maybe I'm not rich enough... After 13 years of banking with FNB, I have to sadly source a new banker.
