Regularly receive calls from this number. They never leave a message and have no ID on their phone number. While I have been blocking the number it still shows as "You missed a call, but the caller did not leave a message."

Potential scammer has used the following phone numbers during the past few days - (02) 8311 9004, (02) 8311 9016. We will never answer the phone when we don't recognise the number so why do they keep calling?

Scam. When you pick up, it ends the call straight away

(02) 8311 9016 I didn't know the number off it

Drongo Scammer.

Ranf
Didn't answer. No message left

This type of call, I suspect is a fishing call test if your number is real with a person. If its, its sold to marketing

Rang several times. No messages left. I'm treating it as scam if they don't leave a return message/comments. Full stop

They call frequently ,no message. Annoying -what do they achieve?.

Call and leave no message
