asked to speak to husband wanted to send something i cut him off!

Someone from this number calls at least once a week, asks for my husband and hangs up when I tell them he is unavailable. The only time I got someone to tell me the type of company, it was oil and gas. Despite repeated requests to stop calling, reporting them to do not call, and informing them I don't talk to scammers, they keep calling. I'm going to start letting them talk to the cat.
