This number keeps calling me but leaving no message. So I have blocked the call. Thanks for letting me know that's its a scam folks.

Just called me, I called scam and hung up. He called back! Pushy. Definitely a scam.

Soliciting donations to support paramedics / ambos.

Definitely a scam. When you call back the number it will not receive incoming calls.

Had this number call me today and try the Police Magazine story with me too. I knew something was going on and hung up.

This number called me as well as another one.
Asked if I would put a "donation" towards advertising my business in a magazine that supports the local Police.
After calling the local Police, I can confirm it was a scam.

Happened same to me. The caller uses different mobile numbers each time which let me to think that it is a scammer. Requesting money/donation for advertising for Austalasian Policing magazine. Later on I got an email from them requesting an email reply to confirm the support which I just deleted.

Tried the same thing on me too

Yep they called me to, I checked with the Queensland police and they've never heard of them. Definitely a scam!

Scam, claims they want to get support for a magazine.

Scam to get money claiming they are from the Police. Getting numbers from the business directory
