didn’t answer. call said it was in nsw.

Call came up "unkown" but said it was from Adelaide (we're in Melbourne). Couldn't be right as it had an 02 prefix, had to be NSW. I don't answer unknown callers, I invite them to leave a message. No message left. Caller blocked.

Calling from Armidale - hung up straight away. Now blocked

Caller: Unknown

Calls received from this number but they hang up as soon as we answer

Unknown Number. Didn't answer and NO message left by Caller. Assume unsolicited caller or scammers

Claimed to be fixing shower heads and exhaust fans in my area tomorrow. I think he wanted to get my details on premise of making an appointment but I hung up before he could finish asking.
Clearly scamming.

Caller: Investor research?

Getting calls from same mob with different numbers

No message left, a few minutes ago. I looked up the area code 0267 on the net which stated South Africa, Botswana.
Definitely scammers.
I always wait to see if a number I do not recognise or is not in my contact list to see if they leave a message, when they don't, they are immediately labeled with being blocked.
These scum should be screened by our telcos so they can't get through. We should not have to put up with this kind of harassment.

We live in NSW and I too do not answer unknown callers and yes they did not leave a message
