Am I Too Paranoid?

Sometimes I wonder whether I am too paranoid. I just got a call, which went like that:

Caller: Hello, we are doing a health insurance survey and have just three questions for you, would you mind to join in? Just 20 seconds. We do it for Health Insurance statistics.
Me: Was in a very good mood SmileSure, shoot
Caller: What is your health insurer?
Me: Gave her the name
Caller: In which year were you born?
Me: What exactly do you need this data for?
Caller: Slightly upset ”As I said: for Health Insurance statistics!
Me: And what company are your working for?
Caller: Hang up

She did not even say goodbye Embarrassed smile

Am I too paranoid with such things? This is my data and I was fairly surprised that she was unable (or unwilling) to answer the questions
