Pending Outstanding Authorisation - Atm Withdrawal

On 01/03/2016 I withdrew funds from my Standard Bank credit card - R600.00. My card was returned by the ATM with an error message, however I still received an sms notifying me that the funds had been withdrawn even though I did not get the money.<br> I called Standard Bank and was told that the query would be resolved.<br> On 02/03/2016 I went to the branch at Gauteng International Airport, where I was told that a query was logged and I would receive an sms with confirmation of the reversal.<br> On 04/03/2016 I received an sms simply stating that the query was resolved.<br> To date, the funds are still not in my account. My statement shows an outstanding authorisation amount of R600.00.<br> It's now costing me to call Standard Bank every day, hold for more than 30 minutes and this issue has still not been resolved.<br> Unacceptable customer service!<br> Can someone please look into this matter and get back to me as a matter or urgency.
