Didnt receive a refund from incorrect billing

In 2012 I app**** for a student loan. The loan was paid off in January 2013, a consultant called to ask on the status of my account and I notified her that the account was paid off, she said that she would close it on her side but she didn't. Standard bank continued attempting to debit from my account but every time it would bounce because I was under the impression that they should no longer try to debit my account. All those bounced debit orders incurred costs for me and in June 2013 I paid 840 towards those unfair charges. I wrote to hello-peter and they stopped debiting my account and my name was cleared, but to this day standard bank has failed to pay me back the 840 I paid towards the so called missed payments.<br> <br> I was told that I would be refunded as it was not my fault that they were debiting my account with no cause. But O am still waiting for them to do what is right.
