When searching this number on reverse call it comes back stating it belongs to Newton, D M and provides the address 105 The Southern Pkwy, Forster NSW 2428.
This is the address for an aged care facility.
I don't know anyone in that facility or associated with this facility.
They keep calling, it keeps going to Voicemail, get told a Voicemail was left.
However, when I listen to it, it's just nothingness for about 30 odd seconds before the message stops.
