Takes Money and Gives Nothing in Return

A week ago I paid a large amount of money into an account which afterwards transpired to be a ********** account. This ********** account is held by Standard Bank; and I paid the money into this account from my own Standard Bank account. The ********** activity was reported to Standard Bank. Standard Bank refuses to give me any further information about this account, or tell me if the funds are in that account. As far as I'm concerned, being a Standard Bank client there shouldn't be any issue in refunding me. However I was told to open a case and send an affidavit. All this has been done. I received an e-mail acknowledging receipt, but nothing further. I've had to phone twice to get an update, and no-one seems able to tell be the status. Today, a week later, I was told that ***** hasn't phone me yet because they don't have my direct line!! This is while I receive daily SMSs from Standard Bank, and I've phoned ***** three times from the same number. Apart form the fact that there is no reason why Standard Bank should not refund me, the service at ***** is absolutely nonchalant and shocking. No information is given. My money is simply not taken seriously.
