This number called three times over a long weekend - always at night after 9 pm. Didn't bother ringing back - an ODD looking number.

Idiot rang at midnight.

Phoned just after midnight, no background noise, stayed on line for approx 1 minute then hung up.
Answered everytime I rang back but hung up each time within 3-15 secs, no voices or background noise, didn't feel like an automated system.
Definitely not a legitimate or genuine caller / number.

I answered the call but no body talk, while the background is pub’s noisy music.

I tried to ring back the number (02) 7201 9415 but reached a silent voice mail
