Same as the rest they don't answer and no message

Call back gets, "Hello, thank you for calling Highland Health Group."  We are calling in response to your recent request regarding health insurance."  Goes on to tell you to press 1 if you're no longer interested in information...."  Well, at least now you know who it is.
