Any other scammer information: Claimed to be from “Greenworld Services’, asked for me by name, asked if I have had someone come to replace my shower head. Claimed it was a free service from Victorian government. (There was a scheme a couple years back that included a bit of a rebate or upgrade, but no straight up free showerheads. And also, I certainly hadn’t organised it, which she claimed I had.) Call was at 5pm in Victoria Australia 15th May. (First ever post, pls let me know if I did anything wrong)
