Unsuccessful withdrawal at ATM

I've been with Standard Bank for more than 15 years now but lately I've been having problems. Last month incorrect amount was debited when I was making a transfer via internet and the money was reimbursed after 3 days but this was after I made endless calls to their customer service. Then on Friday the 25th August 2017 I was making a R2,100 withdrawal at Mall Of Africa, ATM H302. The ATM just went freezing after I've put in my pin and amount to withdraw. It got stuck on "Please wait while we process your request". I didn't get the money or my card. I waited for more than 20 mins with no money or card, then I contacted Std bank customer service. They blocked my card and the consulted assured me that the money won't go off my account and he said it will be reversed within 24 hours if it goes off. They said the ATM will be switched off. I waited for more than 30 mins and the ATM was switched off. Next day I went to withdraw by the teller and noticed that my R2,100 went off and I never got an sms that the money went off. Call was logged with Mall of Africa branch and says it is due on 01 Sep 2017... I'm not willing to wait until the 1st because I need that money.
