Bad service

Got a call from one of their consultants using the number:*** regarding my new application on the medical aid. The consultant was very rude and not ethical at all. I wonder if QA let consultants conduct business in such a manner that is not even professional. It sounded more like running a ****a shop, does Discovery tolerate such mediocrity? The consultant said I will help myself if I'm going to tell her how to do her job, which wasn't even efficient. She was so ***********, raised her voice on me and as I asked for her name, she sighed and kept on singing on the so called recorder line.
