CAPITEC BANK IS OVERCHARGING IN BANKING FEES

I was looking thru my bank statement for the first time and found out that they charging me over R2500 in banking fees when I only did 6 withdrawals at a capitec ATM. they say they have a fixed amount but what is this??? For how long have they been *****ing from me? Who can you trust with your money if you cant evens trust your own bank? Im very dissapointed,
