I received a call from this number twice in the last two days. Hangs up when I give my name.

Called me by my name but when I asked who it was the lady just hung up. Rang back twice but Optus advised that number has been disconnected.

Got a call got disconnected

Have received many calls lately from this number and when I answer there is no-one speaking, just silence. Today I texted back that I had reported the number to relevant authorities as a nuisance caller and left it at that.
