Multiple phone calls --- they never say anything --- 2 to 3 times a day to my OFFICE number at a hospital!! I've been leaving my phone off the hook when they call for about 10 min so hopefully it ties up their line and they'll stop!!
You have to stay on the line for a minute in order for someone to say something. I was about to hang up. Claims it is some census agency wanting to ask questions about health insurance, health care, etc. The lady asked if I had a few minutes to answer questions. I said no I'm at work. Said she would call back later. I asked her not to call back, so we will see if that works.
