Consultant screaming and speaking over me

Today I received a call from the TV license department. The lady was down right rude and unprofessional. She starts off saying I am in arrears and asking why didn't I pay. I ask her when the bill was sent, and she said I should have renewed in December. I'm asking questions to pertain why I missed this, as would have paid had I known it was due. She starts raising her voice at me. I asked why is she shouting and she starts making insulting comments about the fact that the account is in arrears. I told her if she does'nt like her job she should resign as people in call centers should not speak the way she does. If I can liken her tone and attitude to that of a \Taxi rank riot""; and hope that SABC uses those funds to train that women on how to speak and articulate herself correctly on the phone. No wonder no one bothers paying-when you receive harassment calls from obnoxious ;disrespectful consultants of her sort. I am beyond appalled"""
