Absa stalling on refund

On 13 September I attempted to withdraw R1000 from an ABSA ATM. The ATM functioned very slow and clearly needs replacement. The ATM cancelled the transaction before the process was completed. The ATM did not issue any money or a receipt. Although the transaction was cancelled by the ATM, Absa deducted R1000 from my account. I immediately phoned the contact number on the sms notification and I also logged a non-confidential ***** case at Absa in Rivonia on 15 September 2017. To date I received no feedback. Their service is really poor!
