These guys call me almost every day, and sometimes multiple times a day. It's super annoying. Most of the time, I don't answer and they don't leave a message. Usually if I do answer, they hang up on me. Once or twice, a computerized voice will claim to be from some company I've never heard of and I press the button to be placed on their "do not call list" but it never works. Honestly, it's almost to the point of harassment.
