Caller: "Hello I'm Pat, a health care advisor with PDM. I just want to ask you a few questions. Do you currently suffer from arthritis or mobility issues."
Me: I didn't call you. What is your company?
Caller: I'm with PDM.  (Note she doesn't give full name of company).
Me:  I'm sorry, I didn't call you.
Caller:Thank you (Wow, this last reply sounds like a machine and not a real person. Robocall?)
