Upset client (FNB credit card)

I spoke to my private banker who in the month of May asked to move my debit order date for my credit card . She confirm everything is sorted and we good to go. Come the month of June my entire credit card is a mess , I paid into my card R10 000 which they took the intrest out and everything was fine , just letting FNB know I am not in debt and I always pay in more than expected.i also have lots of stuff with FNB as I felt they are my go to bank , example savings , home bond. I login to my account on Friday and no money in my FNB credit card and to escalate the matter urgently. She sends out a mail saying that it will be sorted out Saturday morning with everything in order via mail and I can even contact her via mail or tellphonicallly . So Saturday morning with nothing in my credit card so she advised that I should call or send an mail to her so she can follow up, which I did but never got a response. I have mentioned to her that it's a long weekend and she assured me that this would be sorted . FNB go into my account and see if I ever defaulted all I asked was for a simple change of debit date. Let me know as client should I move my bank as I am not being take care off.
