marked as *potential fraud*

Caller: Clever Contacts

Missed call so I phoned back to get a recorded message stating they are Clever Contacts and that they work with charities. They do direct you to their website so you can look up their privacy statement etc.

I also got the 'Potential Fraud' text on my phone to warn me, once yesterday, and again a few minutes ago. They only ring briefly, and they don't bother to leave a message.
I've reported them, and blocked them.

Caller: (02) 9137 1373

Had two missed calls from this number so I called back and it went straight to an automated message saying I’d called Clever Contacts. I’d seen other comments about this group, so just hung up and added the number to a growing list of ‘Do Not Answer’ in my address book.

I returned a call from (02) 9137 1373 but reached vm for Clever Contacts

Caller: Caller: Clever Contacts

They hung up as soon as I answered. Calling them back directs you to Clever Contacts. It's likely they're calling to test phone numbers under the guise of calling for charity (exempt from the do not call register).

Avoid.
