I usually don't answer calls from numbers I don't know, but I picked this one up. Said hello several times, no answer and they just hung up. Also, would have been nice if they didn't call after 5 pm.

Caller: Red Cross

Looked up on their App for when I'm elegible due to tattoo. Saw I need to ait 4 months, no worries.
Next day they're calling up trying to book an appointment in. Spam

Caller: Red Cross

Answered.. nothing for ages then a recorded message in chinese

Caller: (03) 9278 1615

If they are legitimate why do they hang up so soon and then don’t leave a message?

Caller: (03) 9278 1615

Number has called me 5 times. When I answer there is no one there. Is this a scam? Does my mobile acc get a deduction, such as when I might return a call to Tunisia.

I answered the call but they hung up. I don't know who it was. My phone number is supposed to be on the 'Do Not Call' list.
