FNB Hands you over for 0.55 on revolving loan account that has a debit balance of R214.00 which means they owe you!

I have just spent over an hour on the Secure Chat trying to resolve a query on my revolving loan account for a so-called outstanding amount that reflects nowhere on my account. I have not used this account in a very long time and although the full credit limit amount is available, plus an additional R214.00 which the bank actually owes me and yet, I am being handed over for 0.55 cent with my credit record being affected. I have been transferred back and forth from one agent and department to another without any assistance and after an hour of getting no answers or explanation I gave up. This is ridiculous to say the least and I am now seriously considering closing my business, personal cheque and credit card account along with the revolving loan facility. account.
