Standard Bank Account Query

A debit order was made on the 28th February 2015. I immediately advised standard bank via a telephone call with the General Banking department and requested a reversal be done. I was advised that it will reflect in 48 hours(Business days app****). On wednesday the 4th of March the money was still not reflecting in my account. I gave standard bank a call again(General Banking as this is a cheque account) and they advised that they have done an instant reversal that would reflect the next day - Thursday 5th of March 2015. It is now Thursday and the money is still not reflecting. I come from the Standard Bank - Northgate branch where I was told it would be reflecting tomorrow (Friday 6 March 2015). 1. The money in question is thousands and I need it. This is a serious inconvenience. 2.Of the 5 employees I spoke to none of them had a consistent way forward and the bottom line has been that I will need to wait. I was handed a sheet to sign at the branch but refused as it mentioned the possibility of me incurring extra charges. General manager then requested the employee to sign on my behalf. My consent was not given for this to take place and this is **********.Please advise. Thanks.
