Caller: Unknown but no doubt a scam

Received a from (02) 9202 1941 at 7:20pm which I answered and hung up as an unknown interstate call at this time of night usually means scammers. I rang the number back only to receive a recorded message that the number was 'not connected'. How unusual, ho hum. Just another number to add to the blocked number list. Wish I had a talkative four year old to pass the phone over to, lol.
