Australia Reverse Phone Lookup

I thought it was odd - as soon as I answered there was a delay and they were asking for my father. My dad wasn't home at the time and I asked if I could take a message. They have me he above number and a reference number but wouldn't repeat where they were from and wouldn't say what it was regarding. She asked to ring back before 5pm. I looked up the number - it was linked to Baycorp. Looked up their official page and the numbers didn't match nor did their opening times...

I didn't ring because I had a hunch it was a scam. They got my name wrong. They must have looked in the phone book and guessed my name from my initials.

people saying they are from baycorp ringing about a personal matter and wanting my date of birth and personal details
