INHUMAN TREATMENT FROM FNB

I am banking with FNB for more than 20 years now, I have a car loan with Wesbank that is also part of FNB, I have a Personal Loan and a Revolving Credit Loan, I recently change my profession from a full-time Secretary at attorneys to a Real Estate Agent and went through some tough times, I however still paid all my accounts and even paid my credit car at Nedbank and Loans at FNB in full, I now needed to use the money again, I gained access to all my Personal Loan Funds and they even offer me a further R360 000,00 that I might qualify for, they however blocked my Revolving Credit Loan and I am struggling for a month now to speak to somebody at the Revolving Loan Department in this regard. I am finally done with FNB.
