HIGH FEES

It's common knowledge that people open accounts at Capitec, hoping to save on bank fees. My simple account with them shouldn't cost me so much like now. Looking only at Feb and Mar the picture is different. How do you explain a R9.00 withdrawal fee for R140 vs R8.00 fee for R190 ? In between these are 0.40 notification fee every time there's movement on your account. I only observed 2 mth and I'm convinced that were I to look at other mths it could be worse.
