Money owed by Standard Bank

I am an old customer of Standard Bank and have a tax free saving linked to my check account. I made a transfer last month to my tax free and and it said monthly limit exceeded. I waited for the first and tried it again. I got the same message and out of frustration I attempted it four times on the same amounts and the fourth amount was never reversed. I went into the bank and they could not trace the last amount and decided to send it to the IT department. The IT department showed me the third reversal and said that the money was reversed ignoring the last transfer just under that. They still have the odesaty to charge me for proof of banking details! I wonder how many customers goes through this? Are Standard Bank making money on the side now?
