Caller: scamming scumbags

Calls repeatedly, unknown number to me, disconnects few seconds after phone call answered. Typical behaviour of scammers setting the path for another barrage of harassing and endless nuisance calls.
Australian Govt and service providers surely must be able to put a stop to this abuse of invasive phone harassment by scumbag scammers.

Caller: he called himself "john from microsoft"

he said someone hacking our system, through your IP address, getting data, need to access your pc now to lock them out.......blah blah, thinking I am a non-IT literate person.....how wrong he was.... we are VPN managed and our data is on a non-online-connected SSD/HDD.....we used to be a residential tel number, maybe he was hoping an elderly person and the 'fear' factor was his 'hook'.......this Govt is piss-weak to do anything, just hang up and look after your data......

called but software warning came up so was not snswered

Caller: Some lowlife pretending to be from Microsoft

As other people have said, claims to be from Microsoft saying they have reports someone has attempted to hack my system and I should turn on my computer etc etc. Just hung up on them but these sorts of calls really disgust me as they prey on the weak and vulnerable grrrrr!

Caller: An a**hole from Microsoft

I played along and when I said I owned a Mac he told me I wasted his f#@king time, I am illiterate, a disgrace to my husband and son (I’m not married lol) oh and that I am a horrible woman.

I called the number back it rings but the little rat keeps rejecting my call!

I'll second that Judy B !!
Although the # on my Voip today had a prefix of zero
I have marked my LCD with a fine Artline pen after the 10th.
Anything fore or aft is neglected

Call back and the number is not connected
