Another text message with slightly different Australian number:
If you want to call them from outside Australian then dial: +61 8 7200 0751
If you want to call them from inside Australia then dial: (08)7200 0751
Symbio Networks are the provider for their phone number and are complicit in the scam and refuse to take down the scammers number.
