*****ulant transaction

On 10/4/15, run about 18:00, I transferred an amount of R2000 from my access account to cheque account, and when I tried to withdraw R500, from a different ATM, in Pretoria Centre Walk, Lilian Nqoyi, my card got swallowed by the machine. I did not move from the ATM, and waited up util I phoned the ***** line, suddenly I got an sms confirming that I have withdrawn R2000 of which I did not. I spoke to Bridget from Standard Bank ***** line who promised that it will take only 6 days for response. After 10 days I then called and spoke to Neisa who said that there is nothing that they can do otherwise if Im not satisfied, she will escalate the matter to management. Even up to now, nothing happened and I lost my R2000. Please assist.
