Absa - *****ing my Credit Rating!

I have been a client of Absa for many years. Last month I accidently paid R50.00 short on my credit card. As soon as Absa notified me of this, I paid an additional R1000.00 into my credit card. This all happened in the same month. I know received a report on my credit rating and 17 points were deducted on my name!! I have a clean record and Absa has *****ed it. I will now pay off the card and close it. I don't need more "Edgars" type companies on my name.
