Possible Scam?

Hi everyone,

I got a call from a No Caller ID today, and when I answered and gave my name (as I always do). The person on the phone told me they were from Services Australia and asked me to confirm my date of birth. When I asked why, they said it was 'for my record'. It sounded pretty suspicious... I mightn't have been the kindest when I hung up, believing it was a scam.

Was this most likely the case? I am currently ringing them through the number I get in my letters to see if they tried to contact me.
