could be one of those companies that calls medical offices, pretending to be an insurance company, trying to get the doctors DOB, Tax ID. Soem make up fake "patient" claims in order to get the info. Don't know, but they have called this office and hang up if we don't answer immediately, always sign of autodialers.
Calls from several different numbers, several times a day...told me it was a chiropractic office offering free exam from a doctor's office in our area..the number is from CA and I'm from MI. They are calling a place of business not a personal number!
Same thing. Doctor's Group. I work from home and just this morning (before 10:30 AM) I have received (3) calls from them. I told them they were calling an unlisted number and to stop calling (which my husband also told them recently) and the guy got nasty with me and disconnected. trying to push a chiro office nearby.
