NRB Charge

I posted a complaint on this site on 3 March 2016 regarding an NRB charge that Nedbank has been debiting from my account since January 2016. I received a call from Nedbank consultant on Friday 4 March and she advised me that she would investigate my complaint. I sent her information she requested on even date. I did not hear from her until 7 March 2016 when I sent an email requesting feedback and she advised that she was still awaiting feedback from the relevant department. I find this totally unacceptable, it has been ten days since I logged this complaint and Nedbank is seemingly uninterested in getting this matter resolved.
