Standard Bank useless for securing money

I have been banking with Standard Bank for more than 10 years now and I have trusted them to keep my money safe and secure but it seems like they are only interested in getting money out of you without providing the service they get paid for.

Not so long ago I had an instance where I transferred money into another account and a duplicate transaction was formed which led to 2 transfers being made, I went into the branch to have the one cancelled but I was advised that there will be a charge of R250/R300 to do the reverse otherwise I just have to ask the receiver to send it back, what kind of bank does this?

Recently I have noticed unauthorised debits going off on my account and of course I went to the company involved first to have everything cancelled, today I noticed that these debit orders from ARCADEZONE is still going off on my account every second day or so and as I last resort I called Standard Bank waiting 10 minutes only to be told by the Standard Bank advisor that I will need to pay for the debit order to be cancelled but there is no guarantee that it will stop. How can people still bank with Standard Bank if they are no help with securing money at all! My account is currently -R583.12 due to these orders going off and its ridiculous to pay that much for bank chargers alone!
