I didn't know the number, so I didn't answer, and they didn't leave a message. I called back and got a message for Health First. I don't have insurance with Health First, never heard of them previous to today, and don't know how they got my cell number.
Called and left a message suggesting (did not leave a specific family member name) a post-partum checkup. Caller ID listed it as "ThomsonFinanc" so not sure if this is a trapping call so the person would call back. No debt here whatsoever, so this call was certainly confusing.
