Caller: Lily

Don't know anyone called Lily and don't have the number in my phone book. Not calling back.

Knew my first name and said it was "Shirley" did not give a business name or purpose for the call.
I don't know anyone called Shirley and the number is also unknown to me.

Caller: "Ash"

Left a voicemail which appeared as a transcript on my phone, Hey "my name" its Ash. Call me back when you can. The number is 0489 080 328. Once again the number is 0489 80328, thank you... It sounded like a canadian male speaking, however the number they called from was not the number they left in the voicemail. I don't know a male named Ash so very strange.

Caller: "Shirley"

Also got a voicemail from "Shirley" who knew my first name but left no further info (no business or reason for calling).. told me to call back to a number that was different to the one they called on too.
Australian Lady's voice.

Was apparently a Real estate caller - however was very computer generated, which was obvious by how it would 'ask' questions and couldnt cope with my fast answering.

Sounded very much like an AI bot, I hung up as soon as they spoke
