FNB treat their private clients terribly

As a private client I can't believe how poorly I have been treated by FNB. Two weeks ago I had *****alent transactions on my card. Which shouldn't have happened in the first place as what is the point of having daily limits in place when the ********s can breach them?! Took a few days and multiple hours of waiting for my calls to be answered on their ***** line. Each person I speak sounds tired, disinterested and really couldn't be bothered. I have been refunded the ****** amount (only after kicking up a huge fuss). But the charges that FNB took off my account because of the ***** still have not been reimbursed. Multiple international fees and the penalty they charged me as my debit orders all bounced (as they stole everything in my account - I transferred money across for my debit orders then FNB blocked my account so they bounced anyway!! My banker is not responding to me, her assistant is not responding to me. I have emailed privateclients and they just close my query. This is totally unacceptable!!
