Fnb makes arrangements tat are not valid and take your money anyway

I am currently on UNPAID maternity leave, keyword UNPAID, I was given the option to reduce a payment on my credit card for 3 months and would get until the end of the month o make a payment. I agreed then today the installment amount was taken from my savings the only money I had I call in then speak to clementine mlanjeli who tells me she is sees the agreement but it will not work and the bank can take the installment amount if they want to even if I have an agreement I had agreed to they have a right to just take the only money I hve, which I'm relying on as I can go Into labour at any time and need that money, in 40 years that my family has banked with fnb I have never had a problem and I'm so disgusted at the fact that how can we help you they cannot help and they change their agreements without the clients consent putting a client in even more financial strain. She was appalling a refused to help me with any assistance and said there's nothing she can do. I actually was in tears at the branch
