I never pick up this or similar numbers and immediately block and delete the call notifications and msg txt
Over some months the same number calls 0480012 with changes of the last 3 digits I have had 12 different numbers . Whatever it achieves as a robot dialer is a mystery and it only makes me life j at caller ID on every call . Keep safe and stay @ home .

Whoever they are, they are very persistent- I have blocked the following numbers from this site-
0480 012 434
0480 012 449
0480 012 406
0480 012 396
0480 012 412
I never answer and block them but they then call with another version.

rings but never leaves a message
