99% of this garbage is coming out of Indian criminal call centres. If our Communications Minister would get off his backside and do something about it with his counterparts in that country it could be stamped out.

Caller Lady with Indian accent
Same as above comment from NBN, wanted me to turn on computer and check speed.
I received one call from 0418 567 890 on 21-11-2018, then the following day same query from another number - 0409 567 890. Definitely a scam.

Caller: no one.

Actually 99% scammer. Number has been spoofed. Pity the poor soul whose been spoofed.

Caller: I'm the user of that number

Pretty pissed at these spoofing people catch them and throw the full letter of the communications act at them .
