Caller I.D. identified this number as belonging to "Melissa Michelse." I wasn't able to hear her well, but she first identified herself as someone associated with something sounding to me like Harmony Clinic, and asked me: "Are you the Medicare recipient?" She hung up and did not call back when I asked what she was calling about. This leads me to believe she was involved in something not wholly reputable, but she might well have only been a telemarketer who got a bit thrown off by my aggressive answer to her question.
