Repeated calls where nothing is said - who are these people and what do they want from me ? Getting very annoyed

Don't answer numbers you don't know
If it is important they will leave you a message

Missed a call from this landline - tried to call back but just nothing - no ringing - just silence - this happens a lot to me

looks dodgey, couldn't return the call

They called from this number without leaving any message

(02) 9037 2139 keeps ringing answer & they hang up just let it ring out now.

They just called me and left no message, when I tried to call back there's nothing no ringing just silence.!!??

Asked for Grant Parker and Grant Michael. From a call centre
