It is the Red Cross. It is not a scam. I missed the call and the message left was asking for a blood donation and to call back on their 13 number to arrange a time.

On dialing I get a continuous ring tone which changes to long beeping after a few seconds. Could be the Red Cross blood bank??

I received this call, man said he was from the Australian Red Cross and were looking for blood donors as the van was in the area.

This is probably the Australian Red Cross, I am a donor and received a call from them this morning at home. When I checked my mobile I had a missed call from just prior to the call at home. So I would also guess that is who it is from.

I got a call from this number, picked it up and no answer. Tried to ring back, but there's weird ring tones and no answer. ? scam

When i call them back makes weird noises and funny ringing noise. I dont usaly get this so a bit worried!
