Reversal of Debit Order

I had a Revolving Credit Plan with Standrd Bank, that I settled on the 23rd March and requested to be closed. However, an installment went through on the 29th March even though the loan had already been settled (and in fact the consultant didn't close it, but subsequently closed it on my 3rd visit to the branch). I visited a bank requesting a refund of the said debit order, and a request was sent (I don't know to whom). I received an SMS about 4 days later that my \service request has been resolved\" and that someone was going to contact me shortly, but no one contacted me. I visited the branch again, only to find the \"service request\" was closed with no action. They then processed the refund in the branch and closed the account. The money was supposed to be pain into my Access Account but no money was paid. I was told that they sometimes experience problems in transferring money into the Access Account and if its not there overnight I should visit the branch again. Which I did, but still haven't been paid my money. I used to transfer money between my Access Account and RCP instantly when I was still using the RCP loan. This is the most pathetic service I ever received from any bank"
