No Response from Bank after money disappeared

I have a savings account with Standard Bank which I only use to save in, on 13 March 2015 when I wanted to withdraw money I discovered that there was R 10 000,00 out of my account. I went in the bank where I reported it to the ***** investigators. They informed me that I was a victim of ***** and they would investigate,<br> It would take 6 days to investigate then someone would get back to me. Since the 13th March 2015 nobody from Standard Bank has phoned me or informed me of progress. When I do phone them I hold on for more than 30mins at a time before someone picks up. This is bad service not too mention how money can disappear out of a bank account after all it is the banks responsibility as I still have my card and pin. This only prompts me to withdraw all money out of my account and keep it under my bed where I know where it is, as the bank obviously has no clue as to where the money has gone. I feel ****** and violated.
