Standard Bank Stole My Money!

I have had the worst experience at Standard Bank Florida Johannesburg branch. The ATM did not give me my money after I had entered my instant voucher details and the Manager at the Bank, Mr Naidoo, literally refused to refund me after the ATM people had told him to do so after their investigations! On the 2nd February I went to the bank and put in my voucher number and pin for Instant Money. The ATM accepted the details and then said processing for over a minute whilst the machine was making a terrible noise and then it just went out of order. I stood and stared and waited a few minutes to see if my money would eventually come out but nothing. I took a picture of the ATM showing it was out of order. I then called Instant Money and they logged it for me. Monday the 4th February I went into the bank to follow up and had my first nonchalant, don't care experience from the Manager, Mr Naidoo, who nicely told me I am lucky that his ATM people are coming this week to balance the machines otherwise I would have had to wait another week. He showed no concern and brushed me off telling me to come back Wednesday to check if the machines balanced. I dutifully returned in Wednesday and was then told that actually the turnaround time is 7 working days and that his machines were only R200 over (my voucher was for R1000) but he said he would send an exception. I told him I would follow up on Saturday. On Saturday , the INstant Money people told me they were waiting for his response and he was not at the bank on Saturday. I went again to the branch on Monday 11th February and he once again brushed me off and said it is out of his hands and has done all he could do. I got on the phone to speak to Instant Money and they asked to speak to him. He at first declined to speak to them but eventually took the call! He then advised me to come back the next day. I offered my number to call me but he rather said I should take his number!. I returned the 12th to be told that he will not be refunding me and the ATM people should do so. The bank has officially ****** my money! Please give my money back!
