AUTO BANK TOOK MONEY WITHOUT RECEIPT

I deposited money into my account at Std bank on 9 Feb 2016. The card less autobank took R3 500,00 and closed witout giving me a receipt or anything. I waited there a while and then phoned the number indicated on the machine. I was give a reference number and they told me to wait until the 16th Feb 2016 to investigate. We also reported the incident per e-mail on 12 Feb 2016. They returned the mail and also told me to wait until 16 Feb that they can investigate. On the 16th I received an sms to tell me that they are still busy and I will know what happended as soon as they finalise their investigation. This is not acceptable. On the 17th I send them an e-mail that I am not happy with their service and will escalate the issue. On the 18th a Johanna from the bank suddenly called me about 4 the afternoon to ask me where it happened etc. Clearly they only started now to investigate. This is a small branch and they have cameras there. Surely it could not take this long to investigate and reconcile the auto bank. I am sure I am not the first person this happended to. Bad Servive Standard bank!!!!!
