Shocking service... I am too loyal to FNB

I recently opened a new Private Clients Cheque account with FNB, to my surprise the Premier Credit Card division decided to deduct an instalment from the new account. I never gave consent for this to take place, an arrangement is already in place for the card. I find it very disturbing that no one phoned or confirmed deducting an instalment. Those funds were supposed to go into the business account for a supplier. I also opened a separate investment account with R1m in it - I can choose to move all that to a different bank and close all FNB accounts because I am very disappointed. More so, When I phoned in for a reversal and stepped into a branch, I could not be assisted and was told to call the private clients suite (since I shockingly do not have a go-to guy yet) . I wasted so much time and talk time because I was being put through to various departments. After all that, no resolution!! I still do not have my money back and I still do not have answers as to why that happened. To say the least, I am very, very disgruntled.
