Unhappy client

I am highly upset at Nedbank's incompetence on handling my matter, I spoke to Smangele Vilakazi on Monday regarding an application I made, she advised I need to rectify the matter, which I did on Tuesday. She since has not responded to any of my emails or returned my calls as promised. I only received feedback when I contact her, she will never provide an update. If this is the service I am subjected to I might has well change banks because I will always have to run after the consultants for feedback eve when they promise to contact me. if it was possible my rating will be 0.
