Nuisance Call Reports for 03 9100 3890
A contributor has reported receiving a nuisance call from 03 9100 3890 (also written as 0391003890). The call exhibited automated hang-up behaviour - when answered, the line disconnected immediately without any voice interaction or message. This pattern is consistent with robocalling systems that test whether a number is actively answered before escalating to a live caller or triggering further automated calls.
