Called My Father-in-Law Claiming to be Telstra Tech Support and that his Internet/Modem/Router was causing problems. Said his name was Steven Wilson, FIL said will get my Son to call back as he is Tech expert, so he gave this number (possibly fake) and also his 'Fake' Telstra Id if 107.
He wanted to gain access to the 'Router' as he called it.
Need to stop these Mongrels, thankfully FIL thought to check.
