Got a couple of calls from this number with "Unknown" caller ID. They don't leave a message. I never answer unknown caller that I can't identify by number. My number is in the "Do not call registry". I'll never answer these guys unless they leave a detailed message.
My wife got a call from this # on her cell phone today. 'Total Health Care'. When she asked to speak with someone about getting her cell # removed, they hung up on her. A subsequent call back by my wife got a busy signal.
