rang on the landline and received the following message "optus regrets that the following number is disconnected"

Caller: White Star Finance Group

This number called me and did not leave a message on my mobile. HOW did they get my mobile number? I rang the number back on a spare phone and they identified company name, that they offer property finance! 3 months ago I sold an investment property - this is the closest I have come to property finance.

I called back the number (03) 8373 0349 and reached vm but couldn't hear the company name
