I tried to ring back the number (03) 9278 1615 but reached voicemail for Australian Red Cross

Answered the phone said hello and they hung up without saying anything

Caller: Australian Red Cross Lifeblood

This is a legitimate phone number and organisation. Lifeblood may call existing blood donors from this number to enquire if they are able to donate when there is an urgent need. (For example when your blood matches a particular unwell patient).

Caller: Australian RedCross LifeBlood

RedCross LifeBlood asking for help with donations

That is because it is the Red cross who run the Blood Bank, now called Lifeblood.
As a legitimate caller, they should be required to leave a message,if they are calling past blood donors.

Caller: Red Cross Lifeblood

The calls from this number are asking you to give blood or plasma. A very worthy cause. If you can please book in to give blood or plasma.

Charities such as Red Cross LifeBlood are exempt from the do not call register blocks.

If you a blood donor you're likely to get calls regularly to make new appointments from this number if you haven't given in a while.

calm down

Yes how dare they try to save lives. They should leave you alone to revel in your magnanimity.

No response when I answered the call. If this is ARCBS, it is poor form.

Saw from the comments here that it’s Red Cross lifeblood. I am a donor, so I assume they are calling to remind me to donate. Will save the phone number, but won’t bother calling them back. If they call again, I will answer.

Caller: Australian Red Cross Lifeblood

This is the Australian Red Cross Lifeblood wanting to book me in for another donation appointment.

Caller: Lifeblood representative

Lifeblood notifying me that they will be in my area soon and would I be able to donate blood. A wonderful cause.

Caller: Red Cross Blood Bank

Correct number for the blood bank. They were following up on a qustion I had. Left a message & he was no robot!

Caller: Life Blood

I answered the call but no one spoke anything on the other end and hung up after a few seconds.

If they don't leave a message after calling me then they're blocked, I don't care who they are. I'm a blood donor & if it's Lifeblood then they need to leave a message or not call at all.

Caller: Red Cross, Blood Donations

Legit number/caller. I had an appointment I had to reschedule and this is the number they range me from

Caller: Australian Red Cross LifeBlood

Legitimate call from the Blood Bank, now known as Australian Red Cross Life Blood, wanting to book my next donation. All good!

I answered and said hello and they hung up
