Stupid cold calling call centres

Stupid call centre calling at 8pm at night.

They try anonymous then call from 011113000 after that its an apparently normal number that keeps changing every time. I can only block ten numbers and they only use them once.
I don't know why they keep calling as we are never going to give them a thing.
How long until this crap is not worth their effort then we can have a safe and functional phone system again.
It's funny how technology has made the system worse.
Solve this problem tech industry i don't want new features i want a the end of crap calls.
Come on Jolly roger phone company i want your anti nuisance call technology in Australia.
