Very bad service from FNB

I am self employed and under debt review. For the past 3 months I couldn’t pay towards my debt review or even rent for business and home. I sold my vehicle to just be able to pay towards my debt review as well as my rent that is in arrears and buy a smaller vehicle to be able to still run my business. Money for my car was paid into my account which I’ve transferred in error into my credit card. The amount that was transferred is much more than what is outstanding on my credit card. I’ve been contacting FNB from Friday for assistance and eventually got a case nr. When I contacted FNB again this afternoon after not getting any response back, I was informed that I need to first pay the installment on my credit card before my money can be transferred back into my account. How can I pay for my debt review installment if the only money that I’ve got is in the Credit Card. No one at FNB cares that I really need that money to be able to make a living and that they are just putting me under much more financial strain. I will definitely be moving all accounts from FNB because they definitely not interested in helping.
