This number called me 4 times withing 2 hours. Because my phone rejects unknown numbers, it didn't ring. No messages were left for any of calls.

Caller: Spammer

Had a call from this number on 16/11, one where it's silent for a bit then hangs up. Blocked the number as I always do. Last 2 days have had 8 blocked calls from this number, probably an automated dialer or similar.

Keep calling, have had 5 calls over a few days. Never leave a message

Persistent calling - picked up the first one and after hearing connecting call centre noises (it’s like they’re waiting for contact) and foreign accents I hung up.
Called another 2 times since (within 10min)

Caller: (03) 9118 0929

So many calls! I have blocked the number but I’m still getting missed call notifications.

Dreadfully persistent, guessed it was t/market nuisance caller. Nest time will puck up and scream into phone.

Called 3 times - did not leave a message all times

Didn't answer the call because of suspected spam. Called it back but couldn't connect. Suspicious.

called twice this morning, left no message...
Going by previous comments, good thing I ignored.

Caller: Don’t know

Just left a voicemail yelling hello. Sounds like a call center in the background. Possibly a scam
