Worst Bank in SA

It is the worst bank ever, when it comes to every thing from customer service to actual service I have never dealt with a more *********** bank... I paid up my credit card last month, the end of the month. When the new month came my balance was 0, I was still charged all sorts of charges my balance is now almost R300. I then queried 3 weeks ago they told me they will get back to me within 2 days, nothing. I go back and query they tell me they will get back to me within the day still nothing 3days later. It is now almost month end again, where they will want to charge me on the balance they made. They are now just stalling this query to charge me more. I will be closing this account and will never deal with nedbank again.
