Calls a 3-5 times a week, sometimes twice a day. Always in the day time, between 9am and 5pm. I never pick up. They leave a silent one second message so that your voicemail will notify you when they call. I work for a dental practice.
They keep calling me, don't leave a message, and when I finally answered they knew the address of my former place of employment and stated that they were calling for an insurance company to verify my current location. I hung up.
