I got the same call it happen to be my company's sponsered health coach who did end up leaving me a message. They started a new program last year trying to make the company a more healthy place to work. Hope this helps.
Healthways - health coach, a bunch of nurses/health people contracted by my company's health insurance plan to work with clients to try and hold down health costs.
Had called several times before, but because I receive so many unsolicited/commercial calls on my phone, I hardly ever answer an unknown number unless they leave a message. WHICH THEY DID NOT.
I wish legitimate business services, that have reason to contact me, would LEAVE A MESSAGE so I will know who they are and can either call back or add them to my known contacts.
Twice, on Friday 10/28/2011 between 7:30 p.m. and 8:00 p.m., I got a call from 210-331-2222. I know that this is a "service" set up with my insurance at work, however, they did not respond when I picked up the phone. Then I tried calling back to ask them not to call me at home on a Friday night...four times in a row they hung up on me.
