I got a call from this number - it was a woman telling me she was phoning me back with information on a health insurance quote I had asked for apparently (which I obviously hadn't). I told her I hadn't and she just hung up on me. I called back and a supervisor answered the phone, was actually helpful, and said he'd take me off their call list (he even wanted to know who hung up on me so he could take action but the woman didn't give her name, and I don't imagine he'll be trying too hard to find it). If you get a call and you want to stop them just get the name of the caller before you say anything else to them. Or just block the number if you have a blocker.
Get a call from them at least once a week, with one day they called at least three times. Majority of the time it is a empty message, except this last time where a women asked for us by name.
