Rude call center agents.

I am honestly appalled with the service I have received from Budget insurance and the worst part is having to deal with their rude agents. I have asked to lodge a complaint and the call recording from an agent who was rude, chewing while on the call and talking over me. The lady said her name was Anne, she was a manager, that's what she said when I requested a manager and she dropped the call on me when I insisted to speak to a manager. I called again and requesting a manager or complaints process but I was given the run around, told that "all of the managers are in a meeting. They give excuses when you ask their complaints process and how to get the recording.
