I've had 5 calls from this number over the last few weeks. 2 I missed and the other 3 disconnected when I answered. Not happy.

The message said
"Please hold the line"
"Thank you"
Then hung up

seems like splan

no message left = scam

Caller: Who ever knows ?

sick to death of scammers on my mobile phone. This one rings often. Never the same person. No wonder my mobile says possible fraud. 'then has the gall to ring back because he didn't like being told I wasn't interested.

scam.

i get a call from this number at least 3-4 times a day and I have blocked this .but then it phoenix from a similar number. I just let it ring out

missed call, did not leave message.
when called back it went to voice mail, no company name.

They are called many times and they not talking after say hello they hanged up. I tried to call back but not name on company. I blocked this number from my phone

hangs up when i answer,i called back and went to voicemail
twice now

I returned the call as this number did not leave a message. I received a message please hold please continue to hold then the line went dead. So I assert it is some sort of marketing or bogus company.

I called back number (03) 8579 1703 reached voice mail but did not say for what company.
