Standard bank the worst bank

I called for settlement amount on a revolving loan in mid January which was paid on the same day. After the payment was made i emailed the proof to one of their department and got a response it will be forwarded to the relevant department. Come 31 January an amount is deducted for an account with a zero balance, i wonder why? I call into their call centre spend 20 plus minutes on the line only to be told i need to go into a bank to reverse it. Why should i go into a branch while you have the call centre to assist, i paid R22k so do you think i want to de***** you of R690. This is total bull dust. I was inside you parow branch in this week and spent 1 hour queuing just to change my limit and im not doing it again and this time its not my error. I want this reversal / refund done back into my account and this account closed. If this is not done i'll be speaking to the ombudsman. Im not wasting my time in your branch again on something which is not my error, you quick to penalize when the customer is at fault so whats going to happen in this case. Please also ensure all charges based on this amount is reversed. You guys are the pits and totally useless in the branch.
