Rude telesales agent

A telesales agent phoned to try and sell me a new explora (even though we have one). My daughter answered while I was standing next to her, fixing a door. I could hear what my daughter was saying, and I said that we are not interested. My daughter told the agent that we are not interested where the agent proceeds to tell my daughter "why dont you let your father speak for himself", several times as she was explaining why I cannot talk to her. This after I already declined the same offer earlier the morning from another agent. If this is how a telesales agent treats a customer (or family for that sake), I do not think this is something I would to associate myself with. She also dropped the call as my daughter was explaining why I cant talk. How can you expect someone like that to make sales?
