As a customer I felt mistreated

I was at the bank to make a withdrawal and the new systems of service caused confusion when it skipped my given number, T48. I went to teller no.7 to ask for an explanation and she explained that there was nothing she could do to help me. I insisted that she call her manager, on his (Willie De Beer) arrival he asked no questions but told me to leave because according to him I was causing a scene. I insisted to explain and he threatened to call the police, as if I was a ********. He promised to expel me from \his bank"and deny me access to using Nedbank.This happened openly infront of other customers.<br> <br> When I got home I called for an appointment"
