Absa most expensive bank. Taking more money they they are allowed to

I have a account with absa from I was 4 years old. Suddenly my account is overdrawn but I did not request a limit as I only want to use the money I have.. Someone paid R200 I my account and now it is gone no trais of it in the app. My credit card admin fee is over 442 and the amount hey deduct out my credit card is over 700. This is is not right. The way absa is talking money is not acceptable people are working them self to death just so that you can bankrupt them. Everyone tells me to go to capitc and I now think it is time. Absa is to expensive and greedy. I wnat my money back I did nit agree to any limet as I know how expensive you are
