call centre bad service

I called ADT general enquiries on Saturday at 9.30am, and asked the agent who answered the call about their packages and the price ranges. He said that he was unable to tell me and that they would have to send an agent to my home. I told him that before I have an agent come over I would like to know more about what they're offering and I asked for a more or less idea of the service and cost. He said it was dependant on the area. I told him which area I live in and still he couldn't help. I asked to speak to one of the agents they would normally send out and he said they do not work on Saturdays. I asked a for someone more senior or a team lead or manager. and he said none of these people work on Saturdays. I asked for his name, he mumbled his name and said he was putting me on hold. And that was it., he was gone. Why would I want to do business with people who deliver this kind of service.
