Caller keeps calling. The first time I answered, called asked my name. Doesn't leave a message and has now been blocked

Caller rang at 2:14pm today. Seeing these other comments, I am not surprised to see it is a number for Pareto.
I received a call with the caller ID 'Pareto' yesterday at 2:15pm. I did a search on here, found out they were a nuisance cold-caller for a charity so I blocked them.
So now they are trying on a non-ID number. Nice try. Blocked this number also. Sooner or later they'll run out of numbers to use!

Called, Caller ID is Pareto
No answer.
Charity.

Caller: Pareto

number 0482 160 156 called me at 6:12 pm and didn't leave a msg. The number showed as Pareto on my phone. I looked for company in Google and found a Pareto Pty Ltd that's a telemarketing company in Calloundra QLD. Not sure what they were calling me for as I'm waiting for a call re a complaint about NDIS Local area coordinator in Canberra

Caller: 0482 160 156

No voice then disconnect. Blocked

Caller: Unknown

This is a very persistent number that never leaves a message. Through 101 call back, it is the same male voice saying my first name. "xx, am I speaking with xx?" "is this xx?" Have now blocked it. Sounds like a charity.

Called and didn’t leave a message on voicemail so I phoned back . Automated answer says it’s a charity but not which one so I’ve blocked this number

Didn't answer afraid it was a scamer
