Shocking service from Private Bankers

I've been with FNB for over 6 years now and I hold a private banking account. I've always had a private banker assigned and I have received great service, until about mid last year. I'd send my private banker an email regarding a query I'd have, no replies for days on end. I'd send another email and then I'd get an answer. I see now I've been assigned a new private banker, sent her a query days ago...I am yet to receive a reply. On your adverts you boast about your private banking service, I am sorry, but that is false advertising. At this moment in time I am so disappointed with the service I have received from FNB that I am considering moving my accounts to another bank. Stop advertising a service that you cannot offer.
