staff refusal to compile an investigation,

on the 18 November 2014, I requested an investigation be done by standard bank on one of their employees with regards to them accessing my accounts. <br> On the 1 December 2014, the call center revealed that the investigation was complete and the individual did not access my accounts.<br> I requested the investigation be done again and on the 8 December 2014, I was informed that the individual accessed my business account in October and November. <br> I called again in the 15 December. And I as promised feedback. <br> I received nil, on the 13 March 2015 I went to the gezina branch to find out if it was possible to do another investigation. Their employee Mary Anne informed me that the investigation was completed and they cannot do an investigation again on an employee.<br> I proceeded to rietfontein where it was opened and I was asked to contact KPMG, on the 6 may I spoke to the forensic department, who revealed that the individual went through my personal account on November. Apparently they interviewed her in April. I am shocked and astonished that after 6 months it has been revealed that my personal account has been accessed. No feedback with regards to my business account till this day.
