PRIVATE CLIENTS - Private banker does not get back to you

My private banker is not getting back to me. Today is day 3 of trying to get hold of him. I've been calling, I emailed, left messages, still no call back.

THIS IS WHY I WANT TO DOWNGRADE MY ACCOUNT, so that I am able to speak to FNB employees that are actually able to assist. With Private clients, only your private banker can assist (nobody else), but if your private banker does not get back to you, there is nothing you can do!

Since I downgraded my cheque account, I don't need a private banker so all my cheque account queries are solved immediately. My credit card is Private Clients, and these are were all the issues are.

Can somebody call me back??
