***** - Account hacked

My account was hacked last night (19 March 2015) whilst I was sleeping , 2 payments were made to some absa account R1 200 and R1 500. When I woke up this morning (20 August 2015) I noticed such and I immediately called the ***** call centre to stop payment but was told they can not do so until they have Investigated which may take weeks. What I can't understand is that I as their client am telling them it's ***** and they must stop payment why can't they simply do that? One would expect them to first reverse that payment and then do their investigations. I am really disappointed especially coming from the so called innovative bank.
