They called me and hung up without leaving a message. Likely scammer.

Nuisance caller . No leave msg when call not answered. Red flag given lack of legitimate behaviour - if important enough to make phone call then is important enough to leave msg. No leave msg -> calling number now blocked.

Phone warning spam looking above comments probably true not with Telstra

Said they were from telstra technical suppport. Wanted my computer ip address because my settings had been changed to public from private. Likely Scammer
