I have been getting these calls about everyday for a week, and even some before that. They have called from various area codes. I have never answered any of these calls, and there never has been any voicemail. Today, the same number called three times. I got aggravated. I blocked my number and called it back. It prompted me to enter my number in to remove it from the list. Well, not more than 20 minutes later, the same number called me back! This is extremely annoying!!
