MONEY ****** FROM MY ACCOUNT

Someone stole money from my account without even having my card or my pin on 31/05/2015, this tells me that having an account with Standard bank is not safe. i did not even get an in contact notification when the money came out. I went to the Beacon Bay Standard Bank Branch to find out what happen and report this, they gave me a statement and on there it says that someone withdrew money from my account in central East London, i advised them it was not me and that it be ***** and we need to report this urgently, they told me that i need to contact Standard bank ***** division and they will investigate it and then return my money to me, i did this from the bank and it has gone a month now and they have come back to me advising me that they cannot refund me the money as someone used my card to draw the money, this is impossible as i had my card with me all the time and nobody knows my pin. i am the only bread winner at home, I have two small kids under 5, i need this money returned to me. standard Bank has cameras at all their ATM's, they need to show me proof that i withdrew this money as i know for a fact that it was not me. Reference Number for ***** Case is ***
