An Australian accent male said he wanted to speak to 'my deceased ex name' regarding a personal matter, & left a business number in Melbourne (which reverseau tells me scammers use) (03) 8592 9583
Of course I didn't call, & this mobile number is now blocked

Most likely scam, fraud of some sort.
My phone showed as "Suspected Spam"
I called back and very bad English female answered that I couldn't understand. Something like: " Virtual Gimmick How Can I Help You "
I hanged up straight away.
