DO NOT call this number back! It is a Scammer. Had a missed call but when I returned it I was redirected to a robot voicemail stating no-one was available right now and asking me to call back later. This is a tactic of identity thieves to confirm your phone number is active so they can on-sell your more complete and up-to-date information to fraudsters and scammers to use. If you receive a call from this number or any number with this type of recorded message it's almost certainly the result of your information being stolen in a recent hacking event. DO NOT call this number back as you are confirming your phone number is correct and active to the hackers by doing so. Report the call to the Australian Cyber Security Centre.

Caller: 0483 918 639

I have received numerous calls from this number (up to 2-3 a day) - I have a contact called spam so it is added there, and comes up as spam. The company name is Referral Marketing Guru, and they have now also started calling from 0483 918 639 - appears that they may have a block of numbers that they are calling from

Thank you. I keep getting called by this number around the same time of the day and there is never an answer.
