Standard Bank - Overcharging Bank Charges

Received the latest bank statement for my Standard Bank current account. Immediately noticed that they overcharged me on the service fees. Over and above overcharging me, the total services fees on the statement was 69% more than the sum of each individual service fee on the same statement. Clearly an indication that Standard Bank does not have systems that are accurate. I then went to the Woodlands Boulevard branch to get my concern resolved. The total time from the time that I entered the branch, to the time that I exited the branch , was 75 minutes. A consultant lodged a service request ref. no. ***. The next day, the overcharged service fees was refunded. It is absolutely pathetic of Standard bank to be unable to get simple calculations correct. They then inconvenience customers in having to make the time and take the effort to go to a branch to resolve their mistake. One has to go to a branch, because they don't bother answering the phones. On getting to a branch, one does not get helped speedily. I wondered how many other customers were ****** and overcharged in a similar manner by Standard Bank. My recent experiences with Standard Bank is one that lacks any reasonable customer care, and an ************* bank.
