African Bank... What a disappointment

I've had a credit card with African Bank for over 10 years and during those times the business relationship was good until now. I fell in arrears this year and had to pay an additional R300 which was debited from my bank account. Early in October I got a call from one of their consultants informing me the areas were paid up and they were going to stop the additional payment. It was such a relief however it was short lived since I was then informed of about R80plus arrears of which I asked them to debit R100. My credit card was still not activated and upon calling I was then informed that I owe R531 in arrears. To date noone can explain how I moved from zero arrears to R80 plus then R531 in arrears. One of their line managers from complaints section had said he will escalate the matter and unfortunately 2 months later I am still waiting for that call. Yesterday did an unauthorized debit of R265 leaving me on a minus with my bank. I am so disappointed. To think of how how I was misled by the consultant who informed my arrears were paid up only to find myself still with R531 owing.
