Standard Bank wrongfully transfered money to other

On the 28th of July, Khuniljwa from the set-off department wrongfully transferred money from my savings account into someone else's account. I went into the Mall@Reds branch on 31 July, where a consultant phoned the exact same number I was given to resolve the matter and Jubilant informed us both that the funds will either reflect that day or the following Monday, which it didn't. After numerous phone calls, I eventually on Friday the 7th of August was helped by Steven who processed the refund and sent it to a supervisor as a matter of urgency and that my funds would clear that evening or on Tuesday the 11th. On Tuesday, I still received nothing. I phoned them and they said it would take up to 3 days to process. I waited until today and there was still no refund. Today, I spoke to Tsakane and she informed me that even though the paperwork was submitted, the payment wasn't made. I asked to speak to a supervisor with which I got a response that they will have to call me back because they are all busy. I refused to drop the call until speak to a supervisor. After holding for another 30 minutes, Tsakane returned stating that she went and processed the payment,still no funds reflecting.
