This number rang me - when I answered I heard the phone ringing as if I was the one ringing someone. I immediately hung up. Then I blocked the call on my mobile phone but then I received two unexplained voicemails from presumably the same number. Not sure how that happened.

Called me I answered beeped and hung up, didn’t call back

Keeps calling, tried ringing back but it just beeps. Annoying! will block it now!

Answered the call which switched to my number calling back. Hung up immediately. Scamming through higher charge rate on the call back

keeps calling me, but beeps when I answer and hangs up

Rang twice. Did not leave voicemail message to identify caller, therefore considered non-urgent or telemarketer.

(03) 9001 0013 got 2 calls, no message, called back and got high pitch beep so hung up.

I've also had 2 calls from them today and they have hung up each time. I have not tried calling back.
