Same question I had - how are they getting personal medical info (including my wife's name)? My guess, someone in insurance, medical, or pharma service is selling it. They were a little vague but said they could help with my wife's back or knee pain (my wife has back pain). Still too much coincidence for me. Caller ID: Kate BMQ.
Good guess, everyone has back or knee pain. They apologized and said they had the "wrong patient" But used my name so, not wrong patient. Someone selling this information.
