unauthorised reversal of deposit into my account

once again standard bank has managed to disappoint, yesterday the lady in charge of reversals at standard bank phones me and says that she has made an error and reversed a cash payment of 4087.56 that has been made into my account on the 10th of June 2015 she reversed this cash transfer on the 1st of July 2015 so in actual fact what she has done is taken this amount out of my account and paid it back to the company who has paid it to me and now she tells me that I have to wait until the 3rd of July 2015 when she will call me back to let me know the out come , she does this on the 1st of July when all my debit orders needs to go off and then expects me to wait until the 3rd july for me to get my money back I think this is unacceptable she was supposed to phone me back today the 2nd July 2015 I have not received a call my question is when will my money be back into my account and what is standard bank going to do to rectify this for me I have been with standard bank for many years and to have this type of service is unacceptable.
