Lady called and asked if I knew someone but I didn’t so that was it. She just said she’s from “a company in Perth” suss

I rang back the number (08) 6214 4593 once but got disconnected

From the same number asked for another person's name with my same surname and asked whether I knew this person. when I said no, the lady said thank you and put down the phone

Called and left a message asking if I knew where someone who I do not know was.. very suspicious..

Getting calls from this number and asking for another person living in the street. pretty creepy

I called back the number (08) 6214 4593, rang and got disconnected automatically
